| 摘 要： | 用有限元方法模拟了某大桥锚碇基础深基坑开挖过程。模拟结果表明圆形地下连续墙的拱效应有效地减少了墙体的侧移；施工误差对结构受力和变形有重要影响；墙体嵌岩部分拉应力和压应力都很大。所得出的结论为此类基坑支护结构设计和施工提供了理论依据和实践参考。

| Abstract: | In this article an excavation process is simulated by using FEM. Results reveal that lateral movement of diaphragm is evidently reduced by arching effect; both tensional and compressive stress is very large at wall foot which is socketed into rock; construction error has significant effect on structure displacement and stress. These conclusions provide theoretical basis and practical reference for design and construction of such kind of deep pit. |
