摘要
我国西部高山峡谷地区河床狭窄,作为水电站主体工程之一的泄洪建筑物布置在狭窄河床上,具有“水头高、流量大、流速高”等特点,对流道混凝土衬砌质量提出了极高要求.以白鹤滩泄洪洞混凝土衬砌施工为研究对象,借鉴国内已建成泄洪建筑物运行期的经验,提出了针对施工缝面缺损、错台、漏浆、裂缝等混凝土缺陷的防治及修补措施,经实际运用,取得了较好效果.
Since spillway structure is constructed on the narrow riverbed with high water head and big speed flows,it requires extremely high quality concrete lining of the spillway.Targeting at the concrete lining of Baihetan flood discharge tunnel as study subjects,preventive and remedial measures for concrete defects including construction suture defect,faulting of slab ends,mud leakage and cracking are proposed,with reference to operational experiences of completed spillway structures in China,which has shown a good results after practical implementation.
