大洋拱坝三维静动力有限元分析

By adopting element method analysis, the displacement of dam is analyzed with respect to entire space. The entire dynamic model of dam is established. By taking 4-point freedom element into consideration, perfect interaction simulation between dam and dynamic hydraulic pressure is carried out via user’s program of ANASYS, and the characteristics of arch dam also is analyzed. The structure is calculated based on seismic mode superposition response-spectrum method. The paper will appraise the capability of seismic prevention by adopting the superposition of dynamic response under the earth quack and the calculation under the static situation.
