Non linear static & dynamic finite element procedure is adopted for the true emulation of the four typical geologic profiles of the dam , and imitates to compute the each stage deformation and stress distribution from the dam fill to full water run and during the 7 degree seismic intensity , the article also imitates to compute the response to earthquake force , the excess vibration pore water pressure distribution and permanent deformation , predicting the occurrence possibility of the crac ^ plastic zone and earthquake liquefaction 采用非线性静、动力有限元分析程序对围坝的4个典型剖面进行了静、动力仿真模拟,模拟计算了坝体自填筑至蓄水运行和发生7地震各阶段坝体及坝基的变形以及应力分布,地震应力响应和地震引起的超静振动孔隙水压力分布以及永久变形。判断了坝体和坝基中出现裂缝、塑性区以及地震液化的可能性。

( 3 ) the calculations tell us that the enclose tideland for cultivation dyke effect directly flood drainage , engineering safety and efficiency development in reservoir . so the management of reservoir should be strengthened , the spirit of clearing barriers given by superior should be carried out , clearing barriers in reservoir , especially the enclose dam in west river mouth ( 3 )从计算的结果可知,由于水库库区围堤,直接影响到水库的正常行洪、工程的安全及效益的发挥,应加大水库的管理力度,贯彻落实上级有关水库清障的精神,清除库区障碍物,特别是西河口的围坝。
