摘　　要：进行调压井不同布置方案的对比研究是长距离有压引水式水电站引水线路规划、设计中不可缺少的重要环节。如何选择、合理布置调压井的位置,不仅关系到有压隧洞和压力管道的投资费用多少,而且影响到整个引水系统的工作稳定性。结合某长距离有压引水式水电站,利用特征线法对两种不同典型调压井位置进行了水力过渡过程的计算研究,其结论对长距离压力引水式水电工程的建设有重要的意义。The comparative study of different layouts of surge tank plays an indispensable part in the planning and designing of the long - distance pressure diversion - type hydropower station. Meanwhile, the investment costs of pressure tunnel and pipeline and the stability of the entire work of the diversion system closely relate with the selection and location of surge shaft. This study mainly combines long - distance pressure diversion type hydropower station with two different typical layouts of surge tank by u- tilizing the characteristic curve to calculate the hydraulic transient process, which has great significance on the construction of the long - distance pressure water diversion hydropower project.
