| 摘 要： | 采用ANSYS有限元软件对某软土地区悬臂桩支护基坑进行了二维数值模拟，对基坑周围土体和支护桩随开挖加深和应力释放而产生的变形作跟踪分析，得到了在各开挖阶段桩后地表沉降曲线和桩顶位移曲线，以及在不同地面荷载下桩体的变形曲线，并且分析了变形原因和发展趋势。本文还对基坑土体的破坏机理进行了分析，计算出了土体的破坏位置并探讨破坏机理。

| Abstract: | In this paper, 2D finite element toothed is intruduced to calculate a excavation by cantilevered support located in a weak soil area with finite element software ANSYS. Deformation of soil behind the support piles and the displacement of the pile bolck is obtained in charts and diagrams in process of excavation working, and the deformation of the pile under different ground load is recorded in diagrams. All the change is discussed thorouthly. In the end of the paper, the destoned location in the soil is found and the mechanism of excavation destroy is elaborated fully. |
