摘要
针对南水北调东线济平干渠渠首段存在高水头侧渗、渗水量多、施工困难的问题,采用数值计算和理论分析的方法,提出用深层搅拌水泥土防渗墙进行垂直渗流控制的措施,并运用渗流有限元技术,分析了防渗墙位置对渠道边坡截渗效果的影响,以及不同深度悬挂式防渗墙、封闭式防渗墙对渠道边坡截渗效果的影响,推荐了15 m深的悬挂式垂直截渗方案。
In view of the high lateral seepage water head,big infiltration water volume and difficult construction in the head section of Jiping main canal of the east route of south to north water diversion project,the methods of numerical calculation and theoretical analysis are adopted and deep-mixed cement soil cut-off wall is proposed for vertical seepage control.Based on the seepage finite element method,the cutting seepage effect of channel slope are comparatively analyzed about the position of cut-off wall,not different depth of suspended cut-off wall and closed-end cut-off wall and the 15 m deep of suspended cut-off wall was recommended.
