提出滑块的分合性原则,把双滑块体系的抗滑稳定问题同单滑块的抗滑稳定问题联系起来;提出滑动系数概念,证明了滑动系数符合以重量为权的加权平均原则;以对水平滑面双滑块摩擦模型的研究为过渡,提出了重力坝深层抗滑稳定分析中由K1、K2求K的理论公式;论述了安全系数的介值原则,并以之对现行刚体极限平衡法中的三种方法进行了评判。
The principle of the splitting of the slider is put forward. The sliding stability problem of the double slider system is linked with the sliding stability of the single slider. The concept of sliding coefficient is proposed, which proves that the sliding coefficient accords with the weighted average principle of weight. Based on the research on the friction model of the horizontal slide double slider, the theoretical formula of K for K1 and K2 in the stability analysis of the deep slide in the gravity dam is proposed. The principle of the value of K for the safety factor is discussed. Three methods in the limit equilibrium method were evaluated.
