包括土坝在内的土坝稳定分析方法很多。本文通过一个带有粘土截水槽的斜墙土坝上游坝坡稳定计算实例,对不考虑土条间相互作用力的抗力体法和考虑土条间相互作用力的毕夏普法、推力传递法和分块极限平衡法作了比较和评述,认为对于斜墙坝坡的稳定计算,不宜采用推力传递法。本文推荐了分块极限平衡法,并根据不同情况对抗力体法作了修正。
There are many methods for analyzing the stability of earth dams, including earth dams. This paper presents an example of stability calculation of an upstream slope of an earth dam with an inclined cut-off wall with a clay cut-off. It is based on the resistance method and the Bischap method and the thrust transfer method that do not take into account the interaction force between the soil bars. The block limit equilibrium method was compared and commented. It is considered that the thrust transfer method is not suitable for the stability calculation of slope dams. In this paper, the block limit equilibrium method is recommended, and the anti-force method is modified according to different situations.
