摘要:
试验设置了3种不同的大坝下游坡比、上游坡比、水平趾排水沟长度、自由距高度、坝顶宽度及大坝高度。每次运行都确定了渗流量。结果表明,渗流量随上游坡度、下游坡度、上游水库水深和水平趾排水沟长度的增加而增加,随坝顶宽度和自由距高度的增加而减少。利用 SEEP/W的结果和尺寸分析理论,开发了一种新的简便可靠的经验方程,用于计算带水平趾排水沟的均质土坝的渗流排水量。采用人工神经网络(ANN)法对结果进行分析,表明采用水平趾排水沟的长度是对渗流流量影响较大的几何变量,而土坝的上游坡度影响较小。
Abstract:
The experiment set three different downstream slope ratios, upstream slope ratios, horizontal drainage ditch length, free distance height, dam crest width, and dam height of the dam. The seepage discharge is determined for each run. The results show that the seepage discharge increases with the increase of upstream slope, downstream slope, upstream reservoir water depth, and horizontal drainage ditch length, and decreases with the increase of dam crest width and free distance height. A new simple and reliable empirical equation was developed using the results of SEEP/W and size analysis theory to calculate the seepage discharge of homogeneous soil dams with horizontal drainage ditches. The analysis of the results by artificial neural network (ANN) shows that the length of the horizontal drainage ditch is a geometric variable that has a significant impact on the seepage flow rate, while the upstream slope of the earth dam has a smaller impact.
