| 英文摘要 | In this paper, structure control effect of joint network rock mass on seismic response of underground cavern is investigated. With discussion of the generating principle of 2-d joint network, five characterizing parameters, i.e. as joint density, joint orientation & its discretization, joint trace length & its discretization are identified. The machine hall cavern of Dagangshan hydropower plant is taken as a study case here. The results indicate that in the precondition of a same seismic level, seismic displacement increases with the joint density. Seismic displacement also increases with the joint inclination increase at the range of 0 degrees-80 degrees. If the discretization of joint inclination is considerable, the seismic displacement is of positive correlation with joint inclination discretization, yet if the discretization of joint inclination is comparatively small, this correlation is ignorable. Seismic displacement increases with the joint trace length increase. At last, little relationship between joint trace length discretization and seismic displacement has been found. Those findings may provide certain reference for the aseismic design of the underground caverns. |
