边坡抗滑设计一般采用的是传统强度折减法(如不平衡推力法等),其设计力的依据为不平衡推力等。在分析边坡沿滑面应力分布的基础上,提出了沿滑面3种不同抗滑措施的布置方法;通过对边坡稳定性抗滑设计的计算研究,提出了不同工况下抗滑力的取值方法;结合边坡多参量时空稳定性评价指标,创建了边坡抗滑设计中的分项系数设计方法,并定义了主滑方向和边坡破坏概念。将提出的边坡抗滑措施的布置和抗滑力的取值方法、分项系数设计方法应用于工程(如湖北省十堰市布袋营滑坡)实践,经过多年的运行表明:该抗滑设计的防治措施位置选取、抗滑力的决定及分项系数设计方法是可行的。The traditional strength reduction method (such as the unbalancedthrust method) is generally used in slope control design
and the designcontrol force is based on unbalanced thrust
etc. Based on the analysis of thein-situ stress distribution along the sliding surface of slope
the threelayout methods of control measures along the sliding surface are put forwardsin this paper. Through the calculation and research on slope stability andanti-sliding design
the determination method of anti-sliding force underdifferent boundary (or working) conditions is suggested. With the help of themulti-parameter space-time stability evaluation index of slope
a partialcoefficient method for anti-sliding control design is developed
and thedefinitions of main sliding direction and slope failure are put forward. Theproposed anti-sliding measure layout
anti-sliding force determination andpartial coefficient design method in this paper are applied to the engineering(such as Budaiying slope in Shiyan city
Hubei province). The resultsdemonstrate that the location selection of control measures
the determinationof anti-sliding force and the partial coefficient design method of the slopeare feasible after years of run.
