基于对岩体边坡中地下水的存在性态及作用机理分析 ,提出了实用排水模型 ;建立了排水微分控制方程 ,通过敏感性分析求解此方程而得到岩体中地下水的优化排水方向 .此成果在岩体边坡地下水渗流、库岸边坡岩体中地下水的有效排泄、岩体滑坡有效排水等方面具有重要的实用价值 ,丰富了岩体水力学及山地灾害学的科学内涵 Based on the analysis of the existing state and mechanism of groundwater in rock slope, a practical drainage model is proposed, and the governing equations of drainage are established, and the optimal drainage direction of groundwater in rock mass is obtained by solving this equation through sensitivity analysis. Groundwater seepage in rock slope, effective drainage of groundwater in rock mass of reservoir bank slope, effective drainage of rock mass landslide and so on, which has enriched the scientific connotation of rock mass hydraulics and mountain disaster science
