QI Jun-xiu, WANG Lian-jie, HU Wu-xing, et al. Analysis of stress and displacement characteristics of surrounding rock of underground powerhouse at Xilongchi pumped storage power station[J]. 2008, 29(S1).DOI:
has total installed capacity of 1 200 MW with a rated generating head of 640 m. The three dimensions of its powerhouse are 149.3 m
23.5 m and 49.0 m. The strata in the powerhouse area are composed of argillaceous oolitic limestone
thin banded limestone and thin quartz siltstone with almost horizontal occurrence. The axis of the powerhouse intersects the main faults and fissures with large angles. Displacement and anchor bar stress of the surrounding rock are characterized by obvious anisotropy
and the surrounding rock displacement (mean 3.0 mm) and the anchor bar stress (mean 45 MPa) are relatively small.
