| 摘 要： | 为了简化边坡水平排水孔幕的渗流计算,根据排水孔两侧水位曲线对称的特征,选取隔离体来模拟研究边坡中地下水的运动规律。将排水孔视作强透水的管状渗透介质,建立隔离体的渗流模型,采用数值法模拟分析水平排水孔幕工作时渗流场的分布特征。实例表明,该方法合理有效,可用于边坡水平排水孔幕系统的排水效果评价及边坡水平排水孔幕系统的合理设计。

| Abstract: | According to the symmetrical characteristics of groundwater table in horizontal drainage system,a kind of isolation body is selected to study the law of groundwater movement in the body of slope.The drainage hole is simulated as a type of conductive pipe with strong permeability, the seepage model of the isolation body is establishes. Adopting the numerical method,this paper simulates and analyzes the seepage distribution features of groundwater in the dewatering process of the horizontal drainage holes.It is shown from a practical example that the reasonable results can be obtained,the method can be used in assessment and design of horizontal drainage project. |
