3D Numeriacal Simulation for Slope of the Hydropower Station Considering Multi-conditions
Through the finite difference code FLAC3D, the geomechanical model was established according to the specific geological and topographical conditions at slope of the Hydropower Station. Based on the observed stress data, 3D initial geostress field of research area were simulated. Using it as the primary condition, based on unloading rockmass mechanical theory and method, excavation unloading of slope was analyzed. The excavation condition, unloading condition, reinforcement condition, rainfall condition, creeping condition and sluice condition were considered and compared with monitoring data. The calculating results agreed well with the monitoring data considering different conditions. The result verified the rationality of 3D initial geostress field and the applicability of the method of unloading rockmass mechanics in calculating slope excavation. This research achievement can provide important reference value for similar geological environment projects.
