摘　　要：结合水库输水洞灌浆改造项目,采用冲击弹性波的无损检测技术,对洞内衬钢管若干个断面上的检波点进行灌浆质量检测,分析钢管周围被测检波点处水泥砂浆灌注情况,为评价工程施工质量提供参考。In this paper,the author,by using numerical simulation calculation method,carried out optimizing and selecting type aiming at the parallel unit be composed of two water turbines with different types and sizes,and carried out in detail simulating and analyzing the operation situation for Haili water power station by using new developed evaluation method.The results show that using two different size water turbines can sufficiently increase the electric energy production and investment benefits,and using different size turbines can improve the responsive ability to seasonal discharge variation for the power plant.
