对庙林水电站引水发电系统的阻抗式调压井进行数值法和数学模型水力学计算，并通过模型试验验证数值计算结果的可靠性，论证阻抗式调压井型式可行性。结果表明：调压井数值法和数学模型水力学计算结果与模型试验结果基本吻合；调压井丢弃负荷后的最高涌浪水位低于调压井设计顶高程，最低涌浪水位高于调压井底板高程2.0 m以上；调压井直径、阻抗孔口以及调压井顶高程是合适的，运行过程中不会发生调压井漫顶和漏空的现象。
對廟林水電站引水髮電繫統的阻抗式調壓井進行數值法和數學模型水力學計算，併通過模型試驗驗證數值計算結果的可靠性，論證阻抗式調壓井型式可行性。結果錶明：調壓井數值法和數學模型水力學計算結果與模型試驗結果基本吻閤；調壓井丟棄負荷後的最高湧浪水位低于調壓井設計頂高程，最低湧浪水位高于調壓井底闆高程2.0 m以上；調壓井直徑、阻抗孔口以及調壓井頂高程是閤適的，運行過程中不會髮生調壓井漫頂和漏空的現象。

The surge shaft in the diversion system of Miaolin Hydropower Station is calculated by hydraulic numerical method and mathematical model method respectively and the calculation results are verified by model test to demonstrate the feasibility of throttled surge shaft. The results show that: (a) the calculation results of hydraulic numerical method and mathematical model method are consistent with the results of model test; (b) the maximum surge water level after load rejection is below designed top elevation of surge shaft, and the lowest surge water level is 2 meters higher than the bottom elevation of surge shaft;and (c) the diameter and size of throttled orifice and the top elevation of surge shaft are appropriate and no overtopping and hollow will occur in the operation of surge shaft.
