一、前言渗流计算图表法是一种快速估算均质和非均质土坝渗流量的方法。此方法是在分区计算基础上建立的。由帕夫洛夫斯基研制,哈尔拓展的分区段计算法,是一种近似的渗流分析方法。并能用以决定不同边坡、坝高和坝顶宽度的土坝的渗流量和浸润线的位置,这种方法在计算机上应用很方便。用这种方法所得的渗流量与流网解法相比,平均差为+0.5%。对于核算渗透流量和浸润线的位置,图表解法可获得较好的结果。
I. Introduction Percolation calculation chart method is a rapid method to estimate the seepage volume of homogeneous and heterogeneous earth mines. This method is based on the calculation of the partition established. Developed by Pavlovsky, Haar expansion sub-section calculation method is an approximate method of seepage analysis. And can be used to determine the seepage and saturation line of earth dam with different slope, dam height and crest width. This method is very convenient for computer application. The average seepage rate obtained by this method is + 0.5% compared to the flow network solution. For accounting of permeate flow and saturation line locations, the graphic solution yields better results.
