一、岩体边坡的受力作用 在水工建筑物中岩体边坡一般受到三种力的作用: 1.岩体的重力; 2.作用于岩坡上的主要外部荷载:如重力坝的重力,拱坝推力,以及施工荷载等; 3.由于岩体边坡渗透水流的作用所产生的渗透动水压力。 在对岩坡进行稳定分析计算时,必需考虑这三种力的组合,这是主要荷载,当然还有一些次要的荷载,如浪压力,地震力等。 在上述三种荷载中第1,2两种力都是比较明确
1. The force acting on the rock slope In the hydraulic structure, the rock slope is generally affected by three forces: 1. The gravity of the rock body; 2. The main external load acting on the rock slope: such as gravity dam Gravity, arch dam thrust, and construction loads, etc.; 3. Penetration water pressure due to permeate flow in the rock slope. In the stable analysis and calculation of the rock slope, it is necessary to consider the combination of these three forces, which is the main load, and of course there are some minor loads such as wave pressure, seismic force, and so on. The 1st and 2nd forces are relatively clear among the above three loads.
