摘要
该文以某地杏树沟滑坡工程为例,在对滑坡各要素及变形特征准确识别的基础上,以实际工程的滑壁倾角、滑壁与紧邻滑面夹角、剪出口位置的滑面倾角为基准,以单因素的角度变化计算滑坡的安全系数和剩余下滑力数值,以此分析各角度变化对滑坡安全系数和剩余下滑力的影响规律及各因素的影响系数,对准确识别滑坡和治理工程设计抗滑桩支挡分析具有一定的参考价值.
Abstract
This paper takes Xingshugou landslide in a certain place as an engineering example,on the basis of the accurate identification of various landslide elements and deformation characteristics,it uses the dip angle of sliding wall,the angle between sliding wall and adjacent sliding surface,and the dip an-gle of sliding surface at the shear outlet position as the reference.The angle change of single factor is used to calculate the landslide safety factor and residual sliding force,so as to analyze the influence law of each angle change on the landslide safety factor and residual sliding force and the influence coefficient of each factor,which has a certain reference value for the accurate identification of landslide and the a-nalysis of anti-slide pile retaining design engineering.
