【摘要】 有复杂边界面的渗流场求解问题经常会同时涉及降雨入渗边界和密集排水孔边界,这一般是一个非饱和渗流问题,因此传统的稳定饱和排水子结构模型不能适用。根据 2 类不同的排水孔,给出了排水子结构典型网格划分型式,提出了相应的非饱和排水子结构水力学模型,并引入传统模型中未考虑的降雨入渗等其它边界,使得模型更全面和完善。更多还原

【Abstract】 The problem of solving the seepage field with complicated boundaries frequently involves rainfall infiltration boundary as well as densely-distributed drainage hole boundary. This is in general an unsaturated seepage problem, and therefore, the traditional steady saturated drainage substructure model is not applicable any more. In this paper, according to the two classified drainage holes, typical subdividing modes for the two types of drainage holes are offered and a hydraulic model for unsaturated drainage substructure is presented correspondingly. Additionally, other boundaries like rainfall infiltration boundary which are not considered in traditional model are introduced, making the model more comprehensive and improved.更多还原
