在最新的混凝土面板堆石坝中观察到的渗漏与表面裂缝都与施工期间以及水库荷载作用下填筑料的变形有关。对某些典型的混凝土面板堆石坝的性能进行比较,要求界定混凝土面板堆石坝特有的变形模式。解释了堆石体变形的机理,确定了大坝面板的拉应变区。
The observed seepage and surface cracks in the latest concrete faced rockfill dam are all related to the deformation of the fill material during construction and under reservoir loading. Comparing the performance of some typical concrete faced rockfill dam, it is required to define the specific deformation mode of concrete faced rockfill dam. The mechanism of deformation of rockfill body is explained, and the tensile strain zone of dam faceplate is determined.
