| 摘 要： | 采用反应谱法计算在地震作用下大坝结构的动力响应.对高地震烈度区深山峡谷中的碾压混凝土重力坝的抗震问题,针对其建基面横河向坡度很大的特点,特别计入横河向的水平地震作用,并采用根据承载能力极限状态设计式转换得到的名义安全系数进行稳定复核,得出一些有益的结论.

| Abstract: | The response spectrum method is applied to measure the dynamic response of dam structure under seismic action. As the RCC gravity dam, which is built in deep valley with strong seismic intensity, has a great slope transversal to river direction at its foundation base, horizontal seismic action transversal to river direction is taken into account in anti - seismic design. Nominal safety factors obtained from bearing capacity limit state design formula are used to conduct stability recheck, and some significant conclusions are drawn. |
