穿黄南岸连接段渠道位于黄土地区，工程地质条件复杂，约有2/3的渠段位于地下水位以下，该渠段黄土高边坡高度可达80 m ，属一级建筑物。其黄土高边坡的稳定性是南水北调工程建设中关键的技术难题之一。分析了该地区大量黄土基本试验资料，并选取了计算参数，通过极限平衡法、非线性有限元和动力有限元分析计算了原设计方案进口和出口段黄土高边坡的稳定性，修改了原设计坡型，提出了符合黄土特点的新边坡设计方案。稳定验算结果表明，新设计方案优于原方案。

TheconnectingcanalofsouthbankforCrossingtheYellowRiverProjectislocatedintheloessarea,whichbelongsto class I building w ith complicated geological conditions. About 2/3 of the canal section is located below groundwater level, and the highest height of high loess slope at this segment reaches 80 m. The high loess slope stability is one of key technical prob2 lems in construction of the South2to2North Water Diversion Project. In this paper, a large number of loess fundamental test data intheregionwereanalyzedandtheparameterswereselectedforthecalculationsofloesshighslopestabilityoftheoutletand inletsectionsfromtheoriginaldesignusingthelimitequilibriummethod,nonlinearfiniteelementanalysis,anddynamicfiniteel2 ement analysis. A new slope design scheme was proposed based on the characteristics of loess. The results suggested that the new design is better according to the slops stability calculations.
