隐伏断层及潜在滑动面对工程边坡稳定性影响的研究

Influence of hidden faults and potential sliding surface on the stability of engineering slopes

大量工程案例表明,影响工程边坡稳定性的因素很多,而软弱结构面在决定边坡变形的形成和规模中起着重要的内因作用。应用工程实例,通过节理统计、三大应力(σ1、σ2、σ3)的计算、隐伏断层及潜在滑动面的推断等研究方法,来论述隐伏断层及潜在软弱面对边坡稳定性的影响,并用于工程边坡稳定性评价,对科研和生产具有一定的指导意义。

A large number of cases indicate that the stability of engineering slops are determined by many factors,among which the weak structure as an internal factor defines the formation and scale of slope deformation.In actual project cases,this paper studied the influence of hidden faults and potential weak surface on the stability of slopes and evaluated the stability of engineering slopes by applying research methods including joint statistics,calculation of the three major stress（σ1,σ2 andσ3）and inference of hidden faults and potential sliding surfaces.It is also used for the evaluation of slope stability.The results are instructive and meaningful to future scientific research and production activities.
