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.关键词
