摘　　要：以碗窑水库大坝为研究对象,结合大坝坝体和坝基结构,分析了大坝的渗漏不仅与库区和坝址区地质条件相关,还与蓄水后地下水的动态类型联系密切,重点讨论了水库运行期间影响因素如库水位、气温、降雨和时效等。采用偏最小二乘法回归分析法和统计模型对大坝渗漏的影响进行了定量分析,结果显示坝体和坝基渗漏受库水位影响较大,而U3部位渗漏受气温因素影响最大,研究结果为大坝渗漏防渗处理提供了科学依据。Taking the Wanyao Reservoir Dam as the research object,combined with the dam body and foundation structure,the leakage of the dam is analyzed,which is not only related to the geological conditions of the reservoir and dam site area,but also closely related to the dynamic type of groundwater after water storage.The focus is on discussing the influencing factors during the operation of the reservoir,such as reservoir water level,temperature,rainfall,and hysteresis.The partial least squares regression analysis method and statistical model were used to quantitatively analyze the impact of dam leakage.The results showed that the leakage of the dam body and foundation is greatly affected by the reservoir water level,while the leakage of U3 is most affected by the temperature factor.The research results provide a scientific basis for the anti-seepage treatment of dam leakage.
