Abstract:In humid-tropical and landslide-prone regions,chemical water-rock interaction (CWRI) takes place in various slopes made up of different bedrocks. CWRI can give rise to the progressive aggravation of different initial damages in slopes and the structure,and the mechanical and hydraulic characteristics of mineral,rock and rockmass will all change with CWRI progress. Under many cases,CWRI is the important basis for rainfall or earthquake to trigger landslide events. Despite some attention received and preliminary improvements,the fundamental mechanisms of CWRI have yet to be established. A thorough understanding of CWRI will contribute to landslide mitigation and prediction. The problems necessary to study further include CWRI space,mechanism of water supplying and chemical-mineral relation of CWRI process,the transport theories of water and aqueous matter in low permeable rock,CWRI space spreading,the contribution to landslide preparation process,and so on.
