000010694 520__ $$2eng$$aThe high arch dam has a large orifice size, a compliance shape, and a very complex stress distribution around its orifice under dynamic loading. Therefore, there are many difficulties in the orifice reinforcement design of high arch dams. In this paper, the 3-D elastic Finite Element Method (FEM) is introduced to study the dynamic behavior of the orifice, which is picked out from the entire dam structure, refined and applied with dynamic displacement boundary conditions and dynamic loading of the earthquake. According to the proposed method, more accurate stress results around the orifice than those in the whole structure analysis are obtained. Based on the stress analysis, the quantity of the steel bars around the orifice can be calculated from tensile stress graphs.
