6 FAQs about [Geological work of water storage power station]
What is the lithology of underground powerhouse?
The main conclusions are as follows The lithology of the underground powerhouse is mainly composed of sandstone, conglomerate, and Siltstone. The rock masses have geological conditions for cave formation, and the overall stability of the surrounding rock mass is good.
What is the geological structure of the underground powerhouse?
The geological structure of the main underground powerhouse is simple and there are no regional faults and large-scale faults passing through the study area. According to the statistics of exploring caves in the underground powerhouse area, the main structural planes are rock layers and joint cracks.
How mudstone layers control the stability of a large powerhouse?
The results showed that the stability of the large powerhouse may be controlled by the soft rock (mudstone) layers. The rock mass was classified in terms of the Q classification system, basic quality (BQ) method, and hydropower classification (HC) method, and then the supported system was put forward.
Does support affect excavation deformation in Panlong pumped-storage power station?
Numerical results for the main powerhouse of Panlong pumped-storage power station. Under the supported case, the overall displacement of each monitoring point is basically reduced compared to the under-supported case. the support has distinct restraint effects on the excavation deformation of the iii layer to the vii layer.
What is the elastic wave velocity in underground powerhouse area?
The elastic wave CT in the underground powerhouse area shows that the wave velocity of the rock mass is mainly distributed between 3750–4500 m/s; the rock mass integrity is good.
Why do we need a support system for underground powerhouses?
The support system can effectively reduce the deformation and plastic zone during the excavation of the underground powerhouse. In addition, the supporting setup has obvious effects on limiting the slippage of the soft rock layers.
