Abstract

Through conducting the GDS dynamic triaxial test, this paper makes an analysis for the deformation characteristics of soft soil and its settlement mechanism under the subway traffic traveling load in Wuhan area. The test result shows that the cumulative plastic strain and pore water pressure of the soft clay soil samples are all experiencing the rapid growth stage, the slow growth stage and the stationary stage. The sandy soil samples’ stages are similar to the clay, but its strain value is smaller and pore water pressure value is greater. The total settlement under subway traveling load is consist of settlement caused by the undrained cumulative plastic strain and settlement caused by the dissipation of undrained pore water pressure. Also through the test we can find that the main settlement has completed during the first 3 years, later it becomes stable gradually.
