引水式水电站上下游调压室设置条件探讨

引水式水电站在设计过程中往往遇到因调压室尺寸较大从而造价较高或地质条件不良，需要考虑不设置上下游调压室的问题。而规范中对于设置上下游调压室的条件过于简化。结合最新推导的上下游调压室设置条件，以乐昌峡水利枢纽工程为例，探讨了超规范不设置电站上下游调压室的论证方法。可为今后规范的修订及水电站输水系统合理设计提供参考依据。

Discussion on setting condition of upper and downstream surge chamber of diversion - type hydropower station

In the design process of diversion-type hydropower station,the unfavorable conditions such as large size of surge chamber,higher cost,and adverse geological conditions are frequently encountered,so the cancel of the upper and downstream surge chamber is needed to be considered.However,the setting condition of upper and downstream surge chamber is too simple in the standard.Combining with the proposed conditions of the upper and downstream surge chamber setting,taking the Lechangxia Hydraulic Complex as an example,the demonstration method of canceling the upper and downstream surge chamber,which is not specified in the standard,is discussed.It provides reference for standard revision and reasonable design of diversion water system of hydropower stations.
