摘　　要：采用多元回归分析、流量衰减分析和数值模拟相结合的方法，论证了新安江水电站三坝段扬压力异常机理。研究结果表明，三坝段扬压力异常系局部现象，对工程稳定性不会造成危害性的影响。The mechanism of uplift abnormality within dam section 3 of Xinanjiang hydropower station is studied on the basis of results from regression analysis, discharge rate decay and numerical analog analysis. As a conclusion, it could be stated that the uplift abnormality within the research area is only a local phenomenon, which will not influence on the stability of dam.
