混凝土面板堆石坝坝型对地质、地形适应性强,设计结构简单、填筑速度快,工程造价低,近年来在贵州省水利水电工程中应用越来越广泛,此种坝型在同期新开工的水利项目中比例高达68%左右。但面板堆石坝施工中,混凝土面板裂缝一直都是难以解决的施工技术难题,或多或少均存在不同程度的面板裂缝。文章侧重从混凝土面板裂缝产生原因进行分析,根据裂缝产生原因提出相应的预防和控制措施,以尽量避免裂缝的产生。
In recent years, it has been widely used in water conservancy and hydropower projects in Guizhou Province. In recent years, this kind of dam has been newly developed in the same period The proportion of water conservancy projects started is about 68%. However, in the construction of concrete faced rockfill dam, the crack of concrete slab has been a difficult technical problem in construction all the time, and there are more or less panel cracks in different degree. The paper focuses on the analysis of the causes of cracks in concrete slabs and puts forward the corresponding prevention and control measures according to the causes of cracks so as to avoid the occurrence of cracks as much as possible.
