摘要
Abstract
The concrete face rockfill dam(CFRD)is one of the most competitively powerful dam types now.In order to ensure the safety of high CFRDs the stress and strain behaviors of dam body and concrete face as well as the displacements of joints have become the point of engineering researches.A new type of joint waterstop is put forword and used in several high CFRDs.The mechanical properties of the new type of joint waterstop for high CFRDs are investigated,and a series of stiffness expressions for three-dimension displacements of joints are established.The proposed stiffness expressions can represent the contribution of main components of waterstop to the force transfer from face slab to face slab and from face slab to plinth,and then the influences of arrangement of the high CFRDs on the stress and strain behaviors of CFRDs especially under complex topographical and serological conditions are revealed.关键词
