摘要
In order to discuss the stress state and applicability of closed cut-off wall which is built in the reinforcement project of earth-rock dam,seepage and stress coupled numerical model is established by using ABAQUS.The contact between the wall and the dam together with the coupling of the stress and the seepage are taken into account in the model.Through calculation of a typical earth-rock dam project,the influence of coupling on the stress of the cut-off wall and the stress in different conditions are analyzed.The results show that in the condition of impoundment,the influences of factors such as fluid-solid coupling,elastic modulus of wall materials,modulus of soils and the permeability of foundation on the stress of the wall are quite obvious.
