摘要
本文根据楔形体抗滑稳定计算原理,运用刚体极限平衡法,导出了重力坝深层抗滑稳定空间计算公式。工程实践证明,当坝基内结构面走向和坝轴线有一定的夹角时,运用本文提出的空间方法进行坝基稳定分析是经济合理的。
With the limit equilibrium method for the rigid body, this paper deduces a three dimensional analysis method for the stability against sliding of gravity dam on rock foundations with weak layers, on the basis of the stability against sliding of wedge. The engineering pratice shows that it is economical and reasonable to apply the method given here in to the analysis for the stability of gravity dam foundation with weak layers. in the eare of the dam axis being not parallel to the strike of weak layers therein.
