摘要
Abstract
The tailrace outlet slope on left side of Wudongde Hydropower Plant is a typical steep consequent slope with the maximum height of 114m, and the bedding-landslide prevention is a key problem for slope excavation and support design. Slope ratio optimization and locking support reinforcement were adopted in the construction design period, however due to the complex geological conditions, the exposed rock structure greatly differed from the previous exploration results, thus dynamic reinforce-ment design was conducted. Feedback analysis was conducted for slope stability assessment and FLAC3D was employed to simu-late excavation response of rock mass under unloading condition and study the slope deformation instability mechanism and poten-tial instability modes. Also slope safety factors under different cases were calculated. The simulation results and deformation mo-nitoring indicated that the slope design of excavation and supports was rational and met the specification 's requirements and the slope was stable in general. The slope design process provides reference for similar slope projects.关键词
