Analysis And Computation On 3D-Still Stress And Strain Of Soil-Rock Dam In Xiaban Zone

Rock-fill dam is the one chief type of soil-rock dam, there are much virtue of safety function, adaptability used the local material , be benefit to mechanical building , be short in building time and low in cost, being simple in the building during closure and diversion, etc. It suit the condition of our nation and the environment where the water conservancy works and hydroelectric power plant located , we accumulate the ample practical experience and a series of achievement in scientific research and become a model of having ample competition in the construction and development of piled rock clam.As for Rock-fill dam, there are many dam types based on the method and the material of building dam . The choice dam type is especial importance, during the designed research of the rock-fill dam, particular under the rock-fill dam with very deeply cover layer, the stress and strain of the middle wall and cutting interpenetration wall of the dam foundation is mostly sensitive, whether the .design of dam is scientific and reasonable, it is very important for cutting interpenetration and stability of the dam,, The article offer the reference for the design of cutting interpenetration in the foundation with deep cover with earth the water conservancy in xiaban zone, based on the study and analysis the design of cutting seep in the foundation with deep cover with earth, cutting interpenetration concrete wall and the joining model of cutting interpenetration material in body of dam and the applying effect in the practical worko Based on the foundation which absorbed and summarize the achievement of design and research in the inter and outer country, for the project of the clay vertical middle wall and vertical cutting interpenetration, the asphalt concrete vertical middle wall and vertical cutting interpenetration the clay inclined middle wall and the lever carpet layer cutting interpenetration, respectively in terms of the different stage of complete period sluice period and working condition, adopting nonlinear calculate and analysis with the finite element method; carrying the analysis and study with the 3D finite element method as to the different joining model of the left bank high slope cutting interpenetration body and the foundation concert cutting interpenetration wall ; carrying the analysis and study with the 3D finite element method as to the effect of the wall stress and strain because of the different elasticity modulus of the concert cutting interpenetration wallThrough the analysis and study with the different project .have comparatively all-around comprehended the various model dam, particular the distribute rule of stress and strain of the cutting interpenetration system, provide for the important evidence of the plastic area size the join model of the foundation cutting interpenetrate wall and dam body cutting interpenetrate system the choice of the dam model and the design of the structure of the dam body, the result of research and advice have very importance value in design and building for the similarity project.
