Abstract

Abstract

Based on the test for dynamic modulus of elasticity and test for resistance to liquefaction and seismic performance are analyzed, so as to obtain the shear stress distribution and the distribution of pore water pressure of 0. 6 m thickness;sand pressing method; sand cushion under earthquake loading, combined with sand-sand cushion dynamic modulus and damping ratio test results of liquefaction strength with the move,estimate the anti liquefaction pressure sand sand cushion method, this method has very good practical value.
- immersed tube tunnel,
- sand cushion liquefaction,
- dynamic modulus test,
- liquefaction resistance test
