Estimations　of　the　undrained　shear　strength　(Su)　and　overconsolition　ratio　(OCR)　of　cohesive　soil　are　essential　for　the　evaluation　of　geology　investigation.　In　comparison　to　time-consuming　laboratory　tests,　the　field　piezocone　penetration　test　(CPTu)　can　rapidly　evaluate　these　parameters.　However,　existing　studies　have　mainly　relied　on　empirical　correlations　to　estimate　the　undrained　shear　strength　Su　and　OCR　from　CPTu　measurements.　These　correlations　are　mainly　empirical,　involving　fixed　coefficients　multiplied　by　CPTu　measurement.　Based　on　the　coupled　Eulerian-Lagrangian　method,　this　study　employed　large　deformation　finite　element　modeling　to　summarize　and　extend　the　relationships　between　CPTu　measurement　and　the　estimation　of　undrained　shear　strength　Su　and　OCR　in　cohesive　soils.　These　relationships　allow　for　predictions　based　on　CPTu　measurements　without　the　requirement　for　laboratory　calibration　or　referencing　to　field　benchmarks.　The　accuracy　and　applicability　of　the　proposed　prediction　formulas　are　validated　through　field　case　studies　for　comparative　analysis.　©　2024　Elsevier　Ltd
