Study On The Stress Of RCC Gravity Dam With Layered Structure

Throung analysis and studying on the sandwith structure of RCC gravity dam .A new mothod is used resolving the stress of RCC gravity dam is developed .In order to prove exactness and practicability of the method,This text adopts the material physical parameter of the actual project firstly , employ the thoery of shearing stress mutual equal calculate stress and resist slippery stability of RCC dam with different dam higth and layer modulus of elasticity ;Next,Through to some calculation which plans to build the project of the north of Xinjiang, drawing has sure conclusion of consulting the meaning , has verified practicability and exactness of this method.This method can divide the net to the dam body since , needn't set up the unit among layer , needn't consider the finite element and calculate the magnitude of dividing the unit , Thus reduced the amount of calculation greatly, can asking very convenient solve , go out of dam body each magnitude of stress of position. And can also follow the magnitude of the direct stress and shearing stress ,the method can be used to effectively simulate the continuum cracking and sliding on the interface . The thoery of shearing stress mutual equal not only can use for roll concrete dam , but also can be popularized , used in other layers of form structural interaction research of problem each other.
