Abstract


CSG dam is a cross between the the traditional embankment dam and gravity dam between the new type of dam , it is both the advantages of both dam type , and has its own unique advantages . Essentially advantage of structural safety and stability , rapid construction , the economy , the negative impact on the environment . In foreign countries , especially Japan , the type of dam has attracted great attention and for the actual project and achieved good results . May become a trend in the past 10 years and have developed rapidly. CSG dam construction and promotion of the cause of the development of China 's water conservancy and hydropower will have far-reaching significance . CSG material mechanical properties and RCC similar can be said is a relaxed requirements for ultra- poor RCC . This article RCC dam design theory , virtual one dam model , the use of large-scale general-purpose finite element software ANSYS different dam slope situation , working status of CSG dam , dam stress and strain distribution law as the main computing tool , as well as the overall safety of the dam system of study. Firstly, to collect the CSG dam relevant information at home and abroad , to learn the theory and practical results , CSG material mechanical properties . Then analysis using ANSYS the CSG dam of moving and static performance were compared on 10 different programs CSG dam work behavior , strength and stability in design , summarizes the state of the work of the dam on the downstream slope changes the impact strength, stability under controlled conditions , the problem of how to select dam sectional draw meaningful conclusions . The final selection of the preferred profile , homogeneous soil conditions under different dam material and elastic modulus of the foundation of the dam work state . Final summary of the main conclusions of this work , and put forward the problems and the direction of further development .
