大杠变电站场地古滑坡体应力-应变特征分析

Stress-deformation characteristics of an ancient landslide at Dagang transformer substation site

摘要: 以大杠变电站址古滑坡的工程地质特征为基础，在分析斜坡变形破坏的形成机制及模式的前提下，采用二维弹塑性有限元数学模型分别计算分析了天然及工程开挖回填状况下滑坡体的稳定性．结果表明，天然及工程开挖回填状况下，滑坡体均处于稳定状态．

Abstract: Based on engineering geological characteristics of the ancient landslide at Dagang transformer substation site in Sichuan Province, and on analyses of the formation mechanism and model of the slope deformation failure, landslide stability in both nature and excavation-backfilling is numerically simulated by using 2-D elasticity- lasticity FEM. Results show that the landslide is stable both in nature and excavation-backfilling situations.
