| Abstract: | By use of the 3-dimensional dynamic non-linear FEM, the earthquake response behavior of Nazixia facing sand-gravel dam is researched in detail.The dynamic response properties of the dam are obtained under the designed earthquake action,such as the acceleration response,displacement response,stress response of the dam body and concrete face,as well as the displacement response of the peripheral joints and slab joints.Under the earthquake role of probability exceedance 10% in 50 years,the maximum acceleration... |
