粘性土抗剪强度在基坑支护设计中的应用

Application of shear strength of clay on designing foundation pit bracing

摘要: 针对基坑支护设计中粘性土抗剪强度取值不精确问题,在分析粘性土抗剪强度特征的基础上,提出了应用折算系数法对抗剪强度取值的理论,并以长春市超固结粘性土为例,进行了实际计算和应用,取得了较好效果。

Abstract: On the basis of analyzing character of shear strength of clay,this paper gives a theory that we can use discount coefficient to deal with shear strength aiming at its obtain problem of designing construction foundation pit bracing.Then an example of its appliance is given on super consolidated clay of Changchun City.
