| Abstract: | The tunnel of water diversion from E to WU is in the soft rock. The paper introduces the excavation method, the support parameter, the observation apparatus and the observation result. The observation result shows that the bar screen arch centering, the wire mesh concrete and the concrete base plate with anchor rod play role to the adjoining rock stability. |
