| Abstract: | The rock condition of the underground workshop of Yixing Hydropower Station is undesirable due to the geological structure. To ensure the excavation effect of the rock anchor beam, the grouting shall be conducted and the explosion test shall be made before the excavation of the rock anchor beam. The forming effect of the rock anchor beam excavation of the underground workshop of Yixing Hydropower Station is good, and could be referred by other underground workshops. |
