STUDY ON SEISMIC SAFETY OF XILUODU ARCH DAM

摘要

The anti-seismic performance of large-scale arch dam is one of the key technique factors forrnits design. With the utilization of finite element method (FEM), a solution to the natural vibrationrnproperty of Xiluodu Arch Dam is performed in the paper, and a comparative analysis about therndifference of its natural frequencies with different water level is carried out. Meantime, withrntime-history method, linear elastic dynamic response of the dam under different earthquake waves andrndifferent water levels is solved, and a comprehensive analysis and appraisement to the result is donernfinally.
