本文在对潜滑体边坡工程地质条件进行分析的基础上 ,找出了影响变形失稳的主要因素 ,进行了边坡变形破坏分区 ,并应用快速拉格朗日元法 (FLAC)模拟了地质因素和工程因素共同制约下的潜滑体边坡变形、破坏机理与规律 ,最后运用萨尔玛法 (SARMA)对其稳定性进行了评价与讨论 Based on the analysis of the engineering geological conditions of the submarine slides, the main factors affecting the deformation and instability are found, and the deformation and failure zones of the slope are identified. The fast Lagrangian method (FLAC) is used to simulate Geological factors and engineering factors under the common constraints of the submarine body slope deformation, failure mechanism and laws, and finally the use of Salma method (SARMA) its stability were evaluated and discussed
