| 摘 要： | 针对东圳水库过去设计时没有进行过具体的抗震验算。在土石坝除险加固设计时,利用FLAC3D计算机数值模拟手段对坝体动剪应力、坝体永久变形、坝顶加速度、液化敏感性等进行三维动力反应分析,评价大坝的地震安全性和抗震性能。结果：东圳水库大坝在抗震设防烈度7度情况下其抗震稳定性良好。

| Abstract: | Dongzhen Reservoir was designed without earthquake resistance calculation in the past. So 3D dynamicresponse analysis was conducted by FLAC3D computer numerical simulation during its earth-rock dam reinforce-ment design, to check the dam body dynamic shear stress, permanent deformation, crest accelerated velocity and liq-uefaction susceptibility, and to evaluate the seismic safety and earthquake resistance of main dam. It was concludedthat main dam of Dongzhen Reservoir has good seismic stability under seismic intensity of 7 degree. |
