摘要
采用有限元强度折减系数法,综合位移突变性判据和塑性区贯通判据对某大型古滑坡的稳定性进行了分析。结果表明:综合位移突变和塑性区贯通的失稳判据是一种有效的古滑坡滑面确定办法,可为下一步古滑坡治理方案的确定提供技术支持。
In this paper, the stability of a large ancient landslide is analyzed by using the finite element strength reduction coefficient method,and analyzes the landslide according to the displacement catastrophe criterion and the plastic zone breakthrough criterion. The result shows that the failure judging criterion of the displacement catastrophe criterion and the plastic zone breakthrough is an effective method to ensure the slide surface ofthe ancient landslide, it can provide technologysupport for the determiningtreatment scheme ofthe ancient landslide.
