摘　　要：软土地区超深基坑地下连续墙挡土结构部分的变形大小受众多因素的影响,地下连续墙的变形特征也随着支撑形式和施工方案的不同而有所变化,结合实际工程对地下连续墙的变形因素、变形特性进行监测分析和数值模拟,从而得出了非对称双曲弓形空间侧向变形规律。In soft soil region,the deformation size of the wall which is used as the structure part of retaining is affected by many factors in the ultra-deep pit,the deformation characteristics of the diaphragm wall is distinguished with different support forms and construction programs.Based on the actual project,the deformation factors is analyzed by monitor and the features is analyzed by numerical simulation,we conclude the law of the space lateral deformation is non-symmetric hyperbolic bow.
