基于强度折减有限元法的地下连续墙槽壁稳定性分析
摘要:运用强度折减有限元法对北京地铁16号线西苑站标段地下连续墙槽壁稳定性进行分析,确定了滑裂面位置和滑动体形状,模拟了槽壁失稳破坏的全过程。探讨了泥浆比重、泥浆水头、地下水位、地表均布荷载等因素对于槽壁破坏模式和安全系数的影响。
Abstract:Based on the strength reduction finite element method, the stability of slurry trench of diaphragm in the Beijing metro line 6 Xiyuan station was analyzed. The location and profile of the critical slip surface were calculated. The failure process was also simulated in the commercial software ABQUS. Meanwhile, the effects of various factors such as mud weight and depth, underground water level and surface distributed load were provided in this paper.
