水-岩土化学作用与地质灾害防治

Mechanical Properties of Rock and Soil Influenced by Hydrochemical Action and Geological Hazard Control

水岩土化学作用对岩土力学效应的研究是岩土力学中亟待开拓的研究领域， 此方面的研究及其应用将直接导致地质灾害研究领域中新认识的出现， 并在地质灾害机理与防治研究及环境地质研究等方面具有广泛的应用前景。本文对常温常压下，不同岩石在不同循环流速的水化学溶液中抗压强度的变化进行了试验研究， 主要对水化学作用对岩石的力学效应的作用机理进行了分析， 同时也分析了水化学作用对土体力学性质的影响， 讨论了其定量描述的可能性及扩展到更广泛的应用研究领域的前景， 其中对一些典型的与水化学作用有关的地质灾害作了分析， 并对地质灾害防治的研究思路进行了探讨。

The research on mechanical effects of the chemical action of water rock and water soil has yet to be opened up.This research and its applications will lead directly to a new understand on geological hazard and control research and posses extensive prospects. In this paper, Through the study of the tests on mechanical effects of the chmical action of water-rock mass on the strength of granite and sandstone and limestone, the paper explores the mechanism on their mechanical effect under the different velocity of cycle flow and the different chemical property of aqueous solution.And the effect of the chemical action of water soil on deformation and failure of soil mass is analyzed. The possibilities describing quantitatively this subject and the vast vistas that the research results have application in more extensive research domain are probed into. In view of this, some living examples of geological hazard, and the scientific thinking and methods on geological hazard control are discussed.
