| 摘 要： | 水－岩相互作用研究是力学和地球科学领域中的前沿课题之一。在力学领域中称之为“固流耦合作用”，在地球科学领域中称之为“水－岩相互作用”。前者研究的焦点在于固体和流体间力学耦事的基本规律；后者主要研究在高温高压条件下，岩石和水发生的化学反应规律及其地球化学特征。岩土工程作为土木工程与地质学的交叉学科，水－岩相互作用研究的侧重点以往主要集中于岩体力学方面，即从渗流场和形变场的相互作用角度研究其基本规律，目前，已开始注意到水和岩石的化学作用问题。从工程实践中迫切需要解决的共性课题－－特殊软弱岩体与水作用后力学性能大幅度变异的问题出发，探讨了某些特殊岩体与水作用的化学规律、矿物学规律及其化学与矿物学损伤所导致的力学损伤规律，并建立软岩－水相互作用的时间效应模型；确定软岩性质软化的标志性监界阈值，为建立水－岩相互作用理论体系奠定软岩研究基础，为重大工程的设计、施工等提供有效的参考的指导。

| Abstract: | Research on the interaction between water and rocks has been one of the frontier problems both in mechanics and in the earth sciences.As a crossed discipline of mechanics and geological sciences,geotechnical engineering should pay more attention to the water -rocks interaction,because the stability of engineering rock masses generally is determined by the interacted intensity of water and rocks.In the past two decades,the research of water-rocks interaction has been concentrated on the coupling of seepage flow field and deformation field;and is called hydromechanics of rock masses.From the viewpoint of the authors,the mineral and chemical interaction between water and rocks,especially the damage of the mechanical properties should also be taken into account.In the paper,based on the general problems in engineering practice fields,the authors point out that the key problem of the interaction between water and rocks should be focused on the interaction between water and special weak rocks,and aim at the basic chemical and mineral regularities and the mechanical damage regularities of various kinds of special weak rocks,and build their time-dependent models.At present,the research can be provided as an efficient reference and also a guidance to the design and construction for some major projects. |
