【摘要】 采用二维有限元软件GeoStudio对高土石坝进行动力响应分析,应用等效线性方法计算深厚覆盖层上高土石坝的地震加速度分布情况,对比分析了不同坝高、不同覆盖层厚度以及不同抗震设防烈度下所得到的加速度分布规律。结果表明,以上三方面因素对地震加速度响应均存在不可忽略的影响。更多还原

【Abstract】 In order to study the acceleration distribution of high earth-rock dams on deep overburden foundation,the seismic acceleration distribution laws of the dams are compared and analyzed here with equivalent linear method by using 2D finite element software(GeoStudio) and considering the height of dam,the thickness of overburden layer and seismic intensity.The results show that the influence of these three factors on seismic acceleration response could not be ignored.更多还原
