Influence of Surcharge Preloading Improvement on Surrounding Environment Based on Plaxis 3D

[摘要] In order to evaluate the influence of surcharge preloading on the surrounding environment, the surcharge preloading are numerically simulated in the paper. The results show that: 1) With the increase of surcharge load the maximum horizontal displacement gradually increases. 2) The horizontal displacement is symmetric respect to the center of the distributive load. 3) Due to the existence of drainage surface, the excess pore pressure mainly concentrates between the surfaces and then soon dissipates.
