Abstract

Abstract: According to the actual condition of high-cutting slope of Wushan-Wuxi Road K95 section,general-purpose finite element program ANSYS is used to simulate excavation process.The rock mass' isoclines for stress,displacement etc of excavation before and after are got,and then a comparative test is made.Further,according to the node coordinate of plastic deformation area,latent glide plane equation is got by least squares theory.Hereby,stability evaluation for the high-cutting slope is carried out and effective disposal countermeasures are put forward.

Key words: high-cutting slope, numerical simulation, stability evaluation

摘要： 根据两巫公路K95段高切坡的实际情况,运用ANSYS软件对其开挖过程进行了模拟。得出了开挖前后岩体的应力、位移等值线,并对其进行了对比分析。根据塑性变形区节点坐标,利用最小二乘法原理得出了潜在滑动面方程,据此,对该高切坡进行了稳定性评价,并提出了有效的处置对策。
