摘要

岩体的结构及其透水性直接关系到建筑物围岩的稳定及安全。通过水力劈裂试验，可以真实地反映高水压作用下岩体的结构和渗透性的变化规律。以某水电站工程坝址区岩体所作的水力劈裂试验资料为基础，分析了在水力劈裂过程中，岩体的结构和渗透性发生的变化及其规律以及在该过程中岩体裂隙形成的机理。

Abstract

The structure and permeability of rock determine directly the stability and security of buildings’ surrounding rock. Using hydraulic fracturing tests

the structure and permeability of rock will be shown under high water pressure. On the basis of the hydraulic fracturing tests at the dam site rock of a certain hydropower project

the change and law of the rock’s structure and permeability are analyzed and the mechanism which forms fracture in rock is explained during the hydraulic fracturing.
