摘　　要：为进行水库大坝渗流安全评价,以Autobank软件为媒介,以勘察地质参数为基础数据,对南王水库进行渗流安全复核计算。通过复核结果与现场实际调查结果相比较,进而得出南王水库土石坝的渗流安全评价结论:南王水库坝体上游坝坡采用复合土工布防渗,下游坝脚设有反滤与排水棱体。上游坝坡采用复合土工布有效地减少了水库的渗漏量,坝脚设有反滤与排水棱体有效地降低了坝体浸润线,使浸润线到坝体下游部位渐趋平缓。大坝防渗设施较完善,坝脚反滤、排水棱体设施完善。经分析计算,各工况下,坝体渗透坡降均小于允许渗透,认为大坝渗流性态基本安全。To evaluate the seepage safety of reservoir dam.In this paper,the seepage safety of Nanwang Reservoir was reviewed and calculated by using Autobank software as the medium and geological parameters as the basic data.By comparing the review results with the actual investigation results,the seepage safety evaluation conclusions of Nanwang Reservoir which was the earth-rock dam was drawn as follows:The upstream slope of the dam adopted composite geotextile for seepage prevention.The downstream dam foot was equipped with inverted filter layer and prism drainage.The use of composite geotextiles on the upstream dam slope effectively reduced the leakage of the reservoir.The saturation line which gradually flat tensed to the downstream of the dam of the dam body was effectively reduced with the use of filter layer and prism drainage on the downstream dam foot.The anti-seepage facilities of the dam was relatively perfect,and the inverted filtration and drainage prism facilities at the dam toe was perfect.According to the analysis and calculation,the seepage slope of the dam body was less than the allowable seepage under each working condition.It was considered that the seepage behavior of the dam was basically safe.
