【摘要】 土石坝在建成或拟建的大坝中占有大部分比重,坝坡的稳定性是土石坝工程设计的关键问题,而强震下的坝坡稳定性更是岩土领域中的热点问题.运用ANSYS软件对某一高土石坝边坡进行时程分析,结合可靠度指标计算方法JC法,通过迭代计算得到可靠度指标,进而求得动力可靠度安全系数及最小可靠度指标,其分析结果对高土石坝的动力稳定性分析有广泛的应用价值.更多还原

【Abstract】 Earth-rock dams account for most of the dams which are being built or to be built.The stability of the dam slope is a key issue in the engineering design of the earth-rock dams and the dam of slope stability under strong earthquake is even more the hot issue in the field of geotechnical engineering.The time history analysis was made for a certain high earth-rock dam with software ANSYS.Reliability index was obtained through iterative computations with the help of JC method in reliability calculation method.The safety coefficient of dynamic reliability and minimum reliability index were further obtained,and their analysis result would have wide application value for dynamic stability analysis of high earth-rock dams.更多还原
