摘要
紧水滩拱坝14~#坝段基础廊道上游侧排水沟曾发生1000ml/s的集中漏水,为同时期整个坝基排水量的2倍。本文从钻孔检查情况,坝基排水情况,水质分析成果三方面,分析了漏水成因,得出漏水系坝体混凝土空隙所致的结论。
In the drainage ditch on the upstream side of the foundation gallery at No. 14 dam section of Jinshuitan arch dam occurred concentrated leakage, the volume reaching 1000 ml/sec., twice as much as the drain discharge from the whole foundation for the same period. Based on the drilling examination, drainage analysis for the foundation, and water quality analysis, this paper analyzes the cause of leakage and reaches the conclusion that the leakage resulted from cavities in the concrete of the dam.
