引黄总干三级泵站出水竖井渗漏原因分析及处理

根据水力学渗漏分析计算并结合缺陷检查的情况，确定出具体的渗漏部位，然后采用合理的方法进行相应的渗漏缺陷处理。从渗漏处理的效果可以看出，经过处理渗漏量明显减少，效果显著，可见渗漏分析的结论是正确的，采用的方法是可取的。

Analysis on the Causes of the Leakage of Three-stage Pump Station''''s Outflow Shaft on Main Line of YRDP (Yellow River Diversion Project)

According to the analytical calculations of the leakage by using the hydromechanics and connecting with the defect inspection, the concrete leaking positions are determined, and the corresponding leakage defects are treated by using the rational methods. The results of the leakage treatment show that the leakage is reduced obviously, which illustrates that the conclusion of the leakage analysis is right and the method adopted is practicable.
