摘要

为了探讨岩石在整个变形过程中渗透性变化特点，取三峡永久船闸高边坡花岗岩与山西万家寨水电站高边坡灰岩试样分别进行不同围压条件下全应力-应变过程渗流试验。试验结果表明：岩石在破坏前后不同变形阶段渗流特性具有明显不同；岩石变形过程渗透性与变形破坏形式密切相关。在试验基础上进一步探讨了岩石全应力-应变过程渗流特点之机理，为研究水电工程节理裂隙岩体应力场与渗流场耦合问题提供有价值的支持。

Abstract

In order to probe into seepage characteristics of rocks during their whole deformetion processes

the authors have carried out seepage tests on the specimens of granite which were taken from the high slope at the permanent shiptock of the Tree Gorges Project

and specimens of limestone which were taken from the high slope at the Wanjazhai Hydropower Station in Shanxi Province

under several surrounding pressures.The test results show that the rocks have obviously unlike seepage characteristics before and after destruction of rocks; and the permeability behavior of the rock during deformation has an osculatory correlation with the style of deformation destruction. On the basis of tests

the mechanism of seepage characteristics of complete stress-strain process is discussed further so as to offer the valuable support for the problem of coupling stress field and seepage field of jointed rocks in hydropower projects.
