∶庙林水电站调压室为地下阻抗式，为大型地下洞室结构，开挖内径达21 m，室筒高75 m，顶拱地质条件较差，约1/2为IV类围岩。经对调压室施工、运行期进行有限元分析，最终取消了顶拱球冠的钢筋混凝土衬砌，采用锚喷支护，减小了施工难度，节约了工程投资。施工期及运行初期观测结果表明，调压室变形在合理范围内。

Miaolin hydropower station has a large underground impedance surge shaft, which requires an excavation diameter of 21m and shaft height of 75m. Its vault has poor geological conditions, about 50%of which is Class-IVsur-rounding rock. The reinforced concrete lining of the spherical vault was replaced by anchor-shotcrete support through finite element analysis on surge shaft in construction and running periods, which reduces the construction difficulty and saves the project investment. The results of observations during the construction and running periods show that the deformation of surge shaft is in reasonable limit.
