存在于人类工程活动岩体中的水,对岩体的平衡状态有极为重要的影响,几乎所有的工程岩体失稳都与水的作用有关,三峡水利枢纽坝址区的结晶岩体也不例外。船闸高边坡、地下厂房及坝基岩体的稳定都受水压作用的影响。虽然,所研究的与水压作用有关的工程岩体稳定性问题千变万化,但从水力学的角度来看,最基本的问题就是怎样合理地选取岩体的水力参数。本文首先从岩体中的裂隙入手,用渗透率张量法研究坝址区结晶岩体渗透习性的各向异性变化规律;其次,据岩体的地质特征、物理力学习性和水力习性建立结晶岩地区典型
The water present in the rock of human engineering activity has a very important influence on the equilibrium state of the rock mass. Almost all engineering rock mass instability is related to the role of water, and the crystalline rock mass of the dam site of the Three Gorges Water Control Project is not exception. The stability of ship lock high slopes, underground powerhouses and dam foundations are all affected by water pressure. Although the stability issues of the engineering rock masses involved in the hydraulic pressure study are ever-changing, the most basic issue from the hydraulics point of view is how to reasonably select the hydraulic parameters of the rock mass. In this paper, firstly, starting from the cracks in the rock mass, the anisotropy change law of the infiltration behavior of the crystalline rock mass in the dam site area is studied by the permeability tensor method; secondly, the crystallization rock area is established according to the geological characteristics of the rock body, the physical force learning and the hydraulic habits. typical
