边坡岩体中地下水优化排水机理研究

Research on optimal drain mechanism of underground water in slope rock mass

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得到岩体中地下水的优化排水方向。此成果在岩体边坡及洞室中地下水渗流、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 on features and active mechanism of ground water in slope rock mass, the authors provide a practical drain model in this paper. Then, differential drain dominated equationis. Finally, optimal drain directions are fixed through sensitive analysis to the equation. The results are valuable in course of research on seepage of the underg round water in slope rock mass ,slope stability of reservoir banks and valid drain of rock landslides, which improve the studies of rock mass hydraulics and mountain disasters.
