岩体弹性抗力系数试验难度大，一般只在特大型水电工程有压隧洞中进行。
The experiment on the elasticity resisting coefficient of rock mass is very difficult to be done, so it is conducted only in the pressure tunnel of oversize hydroelectric projects.
有压洞的工作闸门通常布置在隧洞的出口，工作闸门要求常在动水中启闭，检修闸门常在静水中启闭。
The hole in the working gate in the export of tunnel usually decorate, working gate often moving water requirements of opening and closing, often in static water maintenance gate opening and closing.
