摘　　要：根据深基坑工程的施工特点,定义支护结构几何形态时变和材料性质时变两个时变特征及其一般分析方法,基于Monte-Carlo数值模拟技术,建立考虑支护结构几何形态时变的挡土墙变形概率计算方法。工程实践证明,该方法可比确定性数值计算方法更好地反映挡土墙变形特征。Two time-dependent characteristics, namely, geometry type and material properties type, of retaining structure and their general analysis method are defined in accordance with construction features of deep foundation pit. And a probability analyzing method is established for the retaining wall deformation based on Monte-Carlo SFEM. Project practice shows that it can better reflect the deformation characteristics of retaining wall than by deterministic numerical calculation method.
