摘要
加拿大尼亚加拉抽水蓄能电站建成于１９５７年。自１９８７年以来，在大坝桩号ＣＨ４６＋５０附近，先后多次在坝后发生地表塌陷，成为对电站安全评估的关键性问题。该文从水文地质条件分析出发，依据坝后地下水动态监测资料，阐述了地表塌陷的成因机制及其可能的发展趋势。
The Canada Niagara River pumping generating station (PGS) was placed in service in 1957. Since 1987, a series of sinkholes have been detected along the ditch around chainage 46+50. It is necessary to make sure whether or not the sinkholes affect the safety of the dyke. Based on the analyses of hydrological conditions and piezometer response patterns around the reservoir, the mechanism of the sinkholes and the tendency of their development are involved in the paper.
