摘　　要：通过三维有限元软件FLAC-3D对太原市某深基坑的支护结构进行数值模拟,其结果表明:基坑开挖过程中,地表沉降规律为距离基坑由近到远的沉降值是先增加到达最值后逐渐减小,桩身最大水平位移在距离桩顶1/2H处;在桩锚结构中,一定范围内锚杆数量的增加会使支护结构的整体性明显增加。This paper discusses the numerical simulation of the supporting structure of a deep foundation pit in Taiyuan based on the three-dimensional finite element software FLAC-3D.The results show that in the process of foundation pit excavation,the law of surface settlement is that the settlement from near to far from the foundation pit increases first,reaches the maximum value and then decreases gradually,the maximum horizontal displacement of the pile body is at 1/2H from the pile top,in the pile anchor structure,the increase of the number of bolts in a certain range will significantly increase the integrity of the support structure.
