相比于钢筋混凝土(RC)管廊,超高性能混凝土(UHPC)管廊可以减小结构板厚,获得更大使用空间,并可以提升耐久性和使用寿命.为比较两种管廊在受力情况下的损伤机理和破坏模式,以及开裂荷载、刚度、极限承载力和接缝张开量等指标,进行了预应力筋连接UHPC管廊和RC管廊的静力作用下的受力性能试验,并通过有限元模型分析了预应力度对UHPC管廊纵向刚度的影响规律,研究了纵向刚度的简化计算方法.研究结果表明:相较于RC管廊,UHPC管廊的开裂荷载、屈服荷载和极限荷载分别提高了 84%、36%、45.5%;UHPC管廊抗弯刚度大于RC管廊;在达到极限荷载时,UHPC管廊接头竖向错位相较于RC管廊小38.0%,说明UHPC管廊接头性能优于RC管廊,根据有限元分析得到的刚度计算式可为UHPC管廊的设计计算提供依据.

Abstract :
Compared to RC (Reinforced Concrete) utility tunnel, Ultra-High Performance Concrete (UHPC) utility tunnel can reduce structural slab thickness, allow for larger usable space, and improve the durability and service life. To compare the damage mechanisms and damage modes of two kindes of utility tunnels, as well as the cracking load, stiffness, ultimate bearing capacity and joint opening under, the mechanical performance test of the prestressing tendon connected UHPC utility tunnel and RC utility tunnel under the static force was carried out. The effect of prestressing degree on the longitudinal stiffness of the UHPC utility tunnel was analyzed by finite element model, and the stiffness calculation method was also to be explored.The results show that compared with RC utility tunnel, the cracking load, yield load and ultimate load of UHPC utility tunnel increase by 84%, 36% and 45. 5% respectively. And the bending stiffness of UHPC utility tunnel have is larger than that of RC utility tunnel. When reaching the ultimate load, the vertical misalignment of the UHPC utility tunnel joint is 38% smaller than that of the RC utility tunnel, indicating that the mechanical performance of UHPC utility tunnel joints is better than that of RC utility tunnel.The rigid calculation formal of the joints can provide a basis for the design calculation of UHPC utility tunnel. © 2025 Editorial Board of Journal of Basic Science and Engineering.

Abstract :
为了研究柱高比(即为双柱墩中 2根不同高度柱的柱高之比)对非等高RC双柱墩顺桥向弯扭性能的影响,对 2个柱高比不同的非等高RC双柱墩在压弯扭复合受力下进行了拟静力加载试验,得到了双柱墩试件的剪力-位移滞回曲线、扭矩-扭转角滞回曲线以及相应的骨架曲线.基于Abaqus建立了非等高双柱墩的有限元模型,并用试验结果验证了其准确性,随后开展了参数分析,研究柱高比、轴压比和配箍率对弯扭作用下的非等高RC双柱墩顺桥向抗震性能的影响.研究结果表明:柱高比的减小会增大双柱墩顺桥向抗弯承载力,降低了构件的抗扭耗能和抗扭承载力;随着柱高比的减小,扭转效应增强,降低了非等高双柱墩的延性变形能力,且扩大了非等高双柱墩的损伤区域;为避免非等高双柱墩中的矮柱先进入弯剪破坏,建议其柱高比不小于 0.67;轴压比的增大降低了弯扭复合作用下非等高双柱墩的抗弯承载力;增大配箍率可显著提高试件抗扭承载力,对可能受扭的双柱墩可适当增大配箍率.

Abstract :
Due to a lack of seismic design, traditional timber structures make their mortise and tenon joints susceptible to seismic action. To date, there are limited mortise and tenon joints strengthening techniques that are efficient and safe. This study proposed a novel assembled hoop of adjustable stiffness to enhance the seismic resilience of joints. To evaluate the efficacy of this reinforcing technique, two 1/2 scaled Chuan-dou timber structural models were designed, namely intact and reinforced models. The comparative analysis of these models was conducted by shaking table tests. Under a seismic intensity of 8.0, the dynamic amplification factor of the reinforced model decreased by 2.9 % compared to the intact model, and the maximum displacement response decreased by 27 %. This indicates that the seismic performance of the reinforced structure was restored to the same level as the intact structure. Additionally, the interstory drift was reduced from 1/33-1/35. This indicates that the proposed reinforcement technique is feasible and effective in the seismic performance and local joints energy dissipation for the Chuan-dou timber structure.

Abstract :
To investigate the seismic performance of reinforced concrete (RC) double-column piers, particularly unequalheight double-column piers under the combination of compression, bending, shear and torsion in the longitudinal direction of the bridge, five 1:5 scale RC double-column pier specimens were designed and fabricated. The experimental parameters included the column height ratio and the applied displacement ratio by two actuators. The piers with different column height ratios were tested under the quasi-static loading with varying horizontal actuator displacement ratios in the longitudinal direction of the bridge. The results show that the increase of torsional effect by increasing the column height ratio and applied displacement ratio induced the change of failure mode of the test specimens from bending to bending-torsional failure and reduced the bending bearing capacity of double-column piers in the longitudinal direction of the bridge. With an increase in the applied displacement ratio, the torsional bearing capacity, torsional ductility, torsional stiffness, and torsional energy dissipation increased, while the bending bearing capacity and bending ductility and bending stiffness decreased. However, the bending energy dissipation did not decreased significantly (almost unchanged). Additionally, with an increase in the column height ratio, the bending bearing capacity, bending stiffness, and bending energy increased, while the torsional bearing capacity, bending and torsional ductility, torsional stiffness, and the torsional energy decreased, particularly when the column height ratio was greater than 4:3.

Abstract :
Sustainable habitat construction on Mars faces significant challenges, including low atmospheric pressure hindering hydration, reduced gravity complicating compaction, and large habitat pressure differentials. This study presents an integrated In-Situ Resource Utilization (ISRU) approach combining high-strength regolith bricks, hydration-free sulfur bonding, and a modular pyramid habitat design validated by Finite Element Analysis (FEA). Optimized mechanical compaction (40 MPa) of nano-SiO2-enhanced Martian regolith simulant effectively bypasses hydration constraints, achieving compressive strengths exceeding 20 MPa even at ambient temperatures. A systematic parameter study (pressure, particle size, water content, temperature) yielded predictive design equations and demonstrated potential strength enhancement up to 44.5 MPa with thermal treatment (1000 degrees C). Furthermore, a robust, hydration-free sulfur-based mortar was developed for modular assembly; optimized flat-cut interfaces yielded bond strengths exceeding 2.0 MPa, crucially shifting the failure mode from the bond interface to the brick material itself (ensuring a reliable minimum tensile capacity >1.2 MPa). Leveraging these advancements, a pyramid-shaped habitat module, advantageous for Martian environmental loads (including a 101.3 kPa internal pressure differential and 3.71 m/s(2) gravity), was designed. FEA, incorporating experimentally derived material properties (e.g., 22 MPa compressive strength, 1.2 MPa tensile/bond capacity), confirmed the structural integrity, with maximum predicted tensile stress (1.15 MPa) remaining below the bond limit. This research provides a comprehensive, experimentally validated framework-from material development and bonding to structural application-for constructing resource-efficient, durable habitats on Mars, significantly advancing solutions for sustainable extraterrestrial infrastructure.

Abstract :
Current scouring effects and additives increase the risk of failure in underwater structures, and poor observation complicates the identification and assessment of damage. We present a novel index for assessing non-dispersible underwater concrete columns using stress-wave and impedance. A piezoelectric lead zirconate titanate sensor was used to monitor the compression process of non-dispersible underwater concrete columns and ascertain the extent of damage. The proposed index divides the damage process into initial compaction, elastic deformation, and crack development and failure stages. Additionally, the proposed method quantifies and identifies damage, producing results that agree with those for the axial compression failure characteristics.

Abstract :
为探究外包纤维增强复合材料(FRP)加固墩接木柱的加固效果和工作机制,考虑不同纤维布和不同墩接方式等因素影响,开展10根墩接木柱的轴压加载试验.对比分析3种FRP布(AFRP,BFRP,CFRP)、4种不同墩接方式(巴掌榫、刻半榫、抄手榫和直榫)下加固柱的破坏模式和力学性能.结果表明:未采用FRP布加固的传统墩接柱表现为拼接缝木材开裂和开裂后的墩接区木材压屈折断,而FRP布加固后,墩接区整体性良好,破坏主要发生在墩接口,表现为木材压溃和纤维布褶皱;传统墩接柱承载力仅恢复至42% ~69%,刚度恢复至43% ~65%;FRP布加固后,轴压承载力可恢复至完好木柱的75% ~100%,刚度可恢复至66% ~107%,延性提升24% ~96%,加固柱轴压性能和变形能力得到有效的恢复或提高,且刚度退化不明显;此外,有限元仿真得到的荷载位移曲线及力学指标与试验结果吻合良好.FRP加固墩接木柱的轴压力学性能良好,可为传统木结构建筑的修缮和木柱的墩接加固提供借鉴和参考.

Abstract :
To addresses the challenge of underwater grouting sleeve corrosion affecting bridge service life, we propose an innovative inspection approach by integrating a modified ultrasonic testing instrument, ultrasonic data augmentation method, and an improved ensemble learning prediction model. Firstly, the ultrasonic data was collected from grouting sleeve specimens by the modified instrument. Secondly, a data generation model, incorporating Bray Curtis distance and rejection sampling algorithm, was developed to generate samples and filter abnormal data. Then, Circle Chaotic Map improved Grey Wolf Optimizer was proposed to optimize parameters from the Random Forest (RF) algorithm for establishing the prediction model. Finally, SHapley Additive exPlanations (SHAP) method was used to interpret the model globally and locally. Experimental results validate the effectiveness of the data augmentation method, ensuring high-quality ultrasonic data for accurate corrosion rate predictions. The proposed inspection method provide technical support for assessing remaining bridge bearing capacity and service life, showcasing high accuracy, interpretability, and noise tolerance.
