摘　　要：土石坝建设过程中面临的最为关键的问题就是渗漏问题。基于赤金峡实际工程特点建立考虑不同分区的有限元渗流分析模型,对赤金峡水库土石坝进行稳定-非稳定渗流分析,获得水头等值线、浸润线、水力坡降以及渗流量等结果,得出赤金峡水库不会出现渗透破坏。结果对相似工程具有参考和借鉴意义。The most critical issue facing the construction of the earth-rock dams is the leakage problem. Based on the actual engineering characteristics of Chijinxia, the finite element seepage analysis model considering different zones was established. The steady-unsteady seepage analysis of the earth-rock dam of Chijinxia Reservoir was carried out, and the results of water head contour, saturation line, hydraulic slope and seepage flow were obtained. There will be no infiltration damage from the Chijinxia Reservoir. The results have reference and reference significance for similar projects.
