摘要
排水孔幕常用于减小作用于重力坝坝基、拱坝的拱座、地下洞室及岩石边坡的扬压力,由于排水孔孔径太小,受排水孔幕影响的渗流场分析是长期以来未有满意解答的一个问题。本文建议了一种有效的解法,要点是将含有排水孔幕的单元分解成若干子结构,每个子结构含有一个排水孔。本文提出了一种子结构求解方法,并给出一介实际工程的实例分析。
Curtain consisting of drainge-holes is often used to reduce the uplift pressure acting on the base of gravity dam,in the abutments of arch dam,in the rock slope and undergroud excavation.The analysis of seepage field containing a series of drainage-holes is quite a problem solved unsatisfactorily for a long time because of small diameters of the holes.The paper proposes an effective method by dividing the elements of the curtain into substructures,each substructure contains one holes.A substructure approach is suggested and an analysis of a practical problem is also given as an example.
