| 摘 要： | 在软土地区的一些深基坑工程中,坑底加固可以减少围护结构的水平位移及对周边环境的影响,降低坑底隆起和坑底承压水突涌的风险。由于坑底加固的选择往往造成工程造价的增大,利用有限元法对坑底加固方案进行技术优化就十分有必要。针对地铁车站基坑,模型选用了适合土体开挖的Hardening-Soil本构模型。通过对计算出的地表沉降、地墙的水平位移和坑底隆起的比较分析,提出了一些合理建议。

| Abstract: | Soil improvement can reduce the horizontal displacement of diaphragm,lessen the disturbance of surroundings and reduce the risk caused by foundation bottom uplift and inrushing of underground water in some deep foundation programs in soft clay area.Due to the high cost of soil reinforcement,using finite element method to optimize the plan before construction can be very helpful.Based on the hardening-soil constitutive model,the finite element model of metro station foundation is created,and the results of t... |
