Excavation Deformation Analysis of Deep-Cutting High Rock Slope
The mainly purpose of the paper is to investigate the slope excavation deformation of the rock slope at the deep-cutting valley under different load conditions. As an example of the rock slope at the intake of the sluice tunnel of Jinping hydropower station, whose slope deformation characteristics was system analyzed by numerical method during different construction conditions. The dead weight, rain, seism and theirs combination were involved in the numerical analysis. The numerical results could give a reference for the excavation stability of the high rock slope, and it is the basis to determine the reasonable construction method and to optimize the design of the strengthening and enhancing engineering.
