基础薄层长间歇混凝土易受外界影响而产生裂缝,国内已有不少工程实例,因此,一般都避免这种浇筑方法。但故县水库大坝基础,由于地基复杂,固结灌浆量大,同时采用过水围堰,汛期过水不能施工,以及其他一些原因,全部河床坝段共49个浇筑块,从1981年5月开始,历时三年,一般都浇成了薄层长间歇 The basis of long thin-wall intermittent concrete susceptible to external impact and cracks, there are many domestic examples, therefore, generally avoid this pouring method.
