چکیده [English]

In this paper, we present a variety of analyzes in conventional and seismic loading states based on the horizontal component of the earthquake. Then, an attempt is made to assess the tensions occurring before dewatering (empty reservoir), during dewatering (semi-filled reservoir) and after drainage (balance) using classical methods such as simplified mothod (Chievara-fennus) and the modern finite element , In the form of abaqus and cadam software. The principles and methods of design and seismic analysis of concrete concrete weights based on linear and nonlinear analysis. With the attitude to evaluating the concrete weighbridge of Javeh and Pineflat, based on the linear analysis of time histories to the results Decisive in the special The reservoirs at the normal level have been half empty and empty. In the following, the evaluation of the Javau dam is based on nonlinear analyzes using KOBE, KOYENA, CHI-CHI acceleration maps and compares the results obtained in each case. In this area, the elements The tensile strength is more than the tensile strength of the material, and is evaluated along with the position and mechanism of the cracks.
