| 摘 要： | 针对西安地区长乐坡车站的具体工况,应用大型数值分析软件FLAC3D对其开挖支护过程做了模拟研究,分析了开挖支护过程中引起的墙后土体沉降、墙体水平位移、不同连续墙模量以及支撑轴力变化的规律,研究结果表明:1)墙后土体地表最大沉降发生在墙后大约5米处,并形成一沉降槽;2)墙体最大水平位移大约发生在墙高16米处,预应力的增加是由于开挖引起土体变形导致的。 |

| Abstract: | The paper is using numerical analysis software FLAC3D to simulate the excavation and supporting progress of Xi’an Changlepo station.It is analyzing soil subsidence behind the wall,horizontal displacement of the wall,different continuous wall modulus and variation of axial force during the excavation and supporting.The study has proved: 1) the maximum subsidence behind the wall is occurring in about 5meters behind,and there is a subsider behind the wall.2) the maximum horizontal displacement of the wall is appearing 16meters from the wall bottom.While axial force is rising because of the soil displacement during excavation. |
| Keywords: | foundation pit excavation subway station FLAC3D subsidence horizontal displacement |
