Understanding　the　deformation　behavior　of　the　frozen　curtain　during　excavation　is　crucial　when　employing　artificial　freezing　methods　in　construction.　This　study　uses　indoor　frozen　soil　experiments　and　numerical　simulations　to　determine　the　compressive　and　flexural　strengths　of　the　frozen　curtain,　along　with　its　displacement　and　stress　variation　patterns.　Results　show　that　lower　freezing　temperatures　continuously　increase　uniaxial　compressive　strength,　flexural　strength,　and　elastic　modulus　of　frozen　soil,　while　Poisson＇s　ratio　decreases.　Among　the　two　soil　types　studied,　silty　interlayered　with　sand　demonstrates　greater　compressive　strength,　flexural　strength,　and　elastic　modulus.　Numerical　simulation　analysis　indicates　that　the　top　of　the　frozen　curtain　experiences　settlement　during　cross　passage　excavation,　while　the　bottom　exhibits　uplift.　The　safety　factors　of　the　frozen　curtain　were　validated　and　confirmed　to　be　within　safe　limits.　This　study　integrates　frozen　soil　experiments　and　numerical　simulations　to　offer　guidance　for　future　cross　passage　excavations　and　related　engineering　designs.
