摘要: 采用三维有限单元法对强震区高面板堆石坝在施工填筑、蓄水运行和地震情况下的应力变形性状进行了仿真计算,指出在地震时高面板堆石坝的静力和动力应力变形性状的一般规律,并提出了相应的抗震工程措施。Abstract: The stress-deformation behaviors of high concrete faced rockfill dams in strong ground motion zone during construction, water impoundment and earthquake have been imitatively calculated using three-dimensions finite element method. The static and dynamic stress-deformation behavior of dam body, concrete face, vertical joints and perimetric joints of high concrete faced rookfill dams have been obtained. Several corresponding earthquake-resistant measures have been put forward too.
