| 摘 要： | 受复杂地质环境的影响,我国西南岷江上游沿岸普遍发育一种前缘多分布有一层或多层具一定厚度含水砂层的特殊堆积体。大量工程实践表明,工程开挖的扰动可导致砂层出现明显侧向变形,进而导致整个堆积体的失稳破坏。本文采用数值计算的方法,结合某典型堆积体对开挖条件下砂层影响其整体稳定性的作用机理进行了较为深入的分析和探讨。

| Abstract: | Because of the complex geology conditions,there are many special accumulations along the up-reach of Minjiang river,southwest,China. In particular,there one or several seams of sand along the upriver of Minjiang river,southwest,China.Many practices have proved that the excavation will lead the sand seams to emerge big deformation,and then lead the accumulation to fail.This paper presents a FEM analysis on the failure mechanism.It examines how the sand seams affect the stability of the accumulations under the condition of excavation. |
