基于ABAQUS有限元数值模拟的柳河县某高陡岩质边坡稳定性分析
Stability Analysis of a High and Steep Rock Slope in Liuhe County Based on ABAQUS Finite Element Numerical Simulation
摘要
Abstract
The stability analysis of high and steep rock slopes is particularly important for the prevention and control of geological disasters such as landslidesand collapses.Taking a high and steep rock slope in Li-uhe County as an example,the stability coefficient,slope displacement and deformation characteristics of the slope under natural and rainstorm conditions were studied by finite element numerical simulation through ABAQUS.It was found that the stability coefficient of the slope under rainstorm conditions drops from 1.411 to 1.027,which belongs to an unstable state.The maximum displacement is located near the foot of slope and the displacement value increases to 2.178×10-3 m.The maximum strain of the plastic zone of the slope was also located near the foot of slope and extended to the top of slope in an approximate arc shape.In addition,the stability coefficient obtained by simplifying the Bishop method using limit equi-librium theory differs from the numerical simulation results by 6.52%,which was within a reasonable er-ror range,verifying the numerical simulation results.关键词
