摘要
运用FLAC3D软件对武汉长江过江隧道江南明挖段深基坑进行了开挖与支护模拟。计算中采用摩尔-库仑弹塑性模型,基坑围护结构与土体之间的接触面运用接触单元。通过计算得出不同开挖阶段的地表沉降、基底隆起和墙后土体水平位移,为工程设计与施工提供参考。
The simulation of excavation and support on the deep pit of the Yangtze River in south was carded out using the software FLAC^3D. During the simulation, the Mohr-Coulomb model was used and contact elements were applied on the interfaces between the structure and soil. This simulation offers the settlements of ground uplifts in the bottom of the pit and horizontal displacements of the soil behind the vertical wall in every step.
