关于坝基有软弱夹层的重力坝的抗滑稳定计算,是重力坝设计中的一个重要问题,国内很重视这方面的研究,水利水电技术1979年第7期曾介绍这方面的理论及发展方向。并介绍目前进行的三种通常计算方法:被动抗力法,等稳法和剩余推力法。均是按极限平衡理论推导的公式。这三种方法共同之处是均借用坝下址垂直面上的抗力Q,因Q的不同处理方法,产生各种不同的计算结果,如与水平线夹角往往作一些假定,才可求得方程式的解。笔者认
The calculation of the anti-sliding stability of the gravity dam with weakly intercalated dam foundation is an important issue in the design of gravity dam. The research in this area is very important in China. The theory and development direction in this area were introduced in the 7th issue of Water Conservancy and Hydropower Engineering. And introduces the current three kinds of common calculation methods: passive resistance method, equal stability method and residual thrust method. All are based on the theory of limit equilibrium derived formula. Common to all three of these methods are to use the resistance Q on the vertical plane at the bottom of the dam. Due to the different processing methods of Q, different calculation results are produced. For example, the assumption of the included angle with the horizontal is often used to obtain the equation Solution. I think
