摘要
近些年来,国内外的一些面板堆石坝工程相继出现了河床段面板挤压破坏现象,通过对面板挤压破坏机理的分析,表明造成面板挤压破坏的根本原因是堆石的变形,它与坝高、河谷形状、以及堆石的压实状况等因素有着较为密切的关系。严格控制坝体的总体变形,特别是控制蓄水运行后的坝体变形,是避免出现面板挤压破坏的最有效手段。
In recent years, there are some eases of concrete faee slab rupture happened in several high CFRD projects. This is a new phenomena needs to be noticed. From the analysis of the mechanism of face slab rupture, it can be eoneluded that the deformation of rockfilI is the most important reason of the rupture. The rupture of concrete face slab has dose relationship with dam height, valley shape, density of compacted roekfill, etc. Strietly control the total deformation of dam body, especially the deformation after reservoir impoundment, is the most effective measure for avoiding concrete face slab rupture.
