在不连续岩体的岩石边坡上建造电站，高速公路和露天矿所涉及的岩石边坡稳定问题是这些构筑物使用期内最重要的问题。在岩石边坡挖掘中所观察到的一种可能失稳形式是楔体滑动，并且有关其稳定分析的一些数学方法在文献中已有很好的论述。由于大多数所使用的数学方法是基于极限平衡概念，因此似乎需要去检验这些方法在某些控制条件下的有效性。在本文中，作者叙述了一种楔体稳定的方法并将由极限平衡法计算的结果与模型试验的结果相比较。
The construction of power stations on rock slopes of discontinuous rock masses, and the stability of rock slopes involved in highways and open pit mines are the most important issues in the use of these structures. One possible form of instability observed in the excavation of rock slopes is wedge sliding, and some mathematical methods concerning its stability analysis have been well discussed in the literature. Since most of the mathematical methods used are based on the concept of limit equilibrium, it seems necessary to examine the effectiveness of these methods under certain control conditions. In this article, the author describes a method of wedge stability and compares the results calculated by the limit equilibrium method with the results of model tests.
