Study on affecting factors of stress-deformation of diaphragm walls for concrete face rockfill dams built on thick alluvium deposit

The stress-deformation behavior of diaphragm walls of concrete face rockfill dam built on thick alluvium deposit was analyzed using the numerical analysis method.The influences of the properties of alluvium deposit,the properties of diaphragm wall concrete,the construction sequence of diaphragm walls,the distance between diaphragm walls and dam toe and the shape of diaphragm walls on the stress-deformation behaviors of diaphragm walls of concrete face rockfill dams were studied.Some laws and corresponding engineering proposals were also put forward.
