破坏滑动面 meaning in Chinese

slip surface of failure

Based on analysis of the characteristics of the composite soil nailed wall , simulating the soil nail , concrete layer , deep mixing pile and step excavation , a model is established to calculate the deformation of the wall , compiled simple and applied program of one dimension fem ; according to the field test data and the calculated data by the fem software this paper has developed , the design method and deformation of the wall in xi ' an area is discussed . the shape of destructive sliding surface of the wall in loess strata in xi ' an area with deep groundwater is gotten . finally the lateral deformation distribution and the experiential formula to predict maximal horizontal displacement of the composite soil nailed wall are given
针对复合土钉墙构造的特点，建立了模拟复合土钉墙受力变形的一种计算模型，该计算模型可对土钉、面层、深层搅拌桩以及分层开挖等进行简化模拟；编写了简单实用的杆系有限元程序；结合工程实测资料及有限元法分析的结果，探讨了西安地区的土钉设计以及复合土钉墙的变形规律，得出了西安地区一般黄土在无地下水时的破坏滑动面形状，复合土钉墙的侧向变形曲线以及计算复合土钉墙最大水平位移的经验公式。
