Pumped Storage Power Station[J]. 2006, 27(S2).DOI:
Taking the excavated slope at powerhouses of Wuxi Mashan Pumped Storage Power Station for example
the corresponding geological profiles are analyzed in detail; and the possible slides are found out. Using the limit equilibrium analysis and finite element method
the stability and the relationship between stress and strain of four profiles are analyzed. The results show that the values calculated by limit equilibrium method and FEM are closed; and they are satisfactory with GB standard; the maximum displacement of slope occurs at the elevation of -20m and 5m
the value is -22 mm; its maximum principal stress is located at the elevation of -45..0 m
and its value is 0.134 MPa; the minor principal stress is -6.22 MPa. In addition
the time-dependent characteristics of the slope should be discussed in future study.
