摘　　要：对西安市某均质土坝,库水位在最高水位的工况下,用有限元分析软件Geo-slope计算分析了背水面不同高度的透水边界对渗流场和背水面边坡安全系数的计算结果的影响。结果发现,背水面透水边界在合理的高度以下上升时总流量、出溢流量、出溢口处水力坡降、背水面边坡安全系数增大;背水面透水边界在合理的高度以上升高时这四个代表值减小。说明了合理的背水面透水边界为各个流场代表值和边坡安全系数的极值点。Based on a homogenous soil dam at a highest water level,the effect permeable conditions on the seepage and the water dorsal slope＇s stability is of various dorsal surface analyzed with Geo-slope. The result shows that the total flux, the overflow flux,the gradient at the overflowing point and the water dorsal slope＇s safety factor grow while the permeable condition lifting under the realistic height. These four characters drop while the permeable condition lifting that the height of the realistic permeable condition represents the over the realistic point.It demonstrated extremum of the four characters.
