摘要
本文采用FLAC软件,通过建筑物基坑随开挖深度增加而变形的模拟,得出基坑每一阶段开挖及土钉支护条件下的位移发展演变规律,跟踪最大不平衡力变量的变化提出了最佳土钉支护时机。
In this paper, the authors carried out a numerical simulation towards deformation along with the excavation using FLAC^3D. We obtained the rule of the displacement distribution under the condition of excavation and soil nail supporting, at the same time we put forward the best time of the soil nail supporting according to the change of the maximal unbalanced force.
