摘要
以高层水电站为例．介绍了高层水电站在施工过程中，因输水系统地质等因素变化而引起建筑物结构改变，从而使得原设计调保计算得不到满足的情况，然后应用导叶分段关闭方法进行调保计算，达到了满意效果。
Taking the Gaoceng Hydropower Station for example, the unsatisfied situation of the regulating guaranteed calculation condition for the original design scheme caused by geological variation and thus the structural variation of the water delivery system, is introduced. And the method of stage closing of guide blads is applied to solve the regulating guaranteed calculation problem. Its effect is fairly good.
