《南水北调与水利科技》：济平干渠渠首引水闸优化设计(李贵清,田间,季安,张兴珏)(摘要)

摘要：济平干渠渠首引水闸是沟通南水北调东线之南北输水干线和胶东输水干线的控制性工程。施工现场条件复杂，原方案采用闸后3孔整体式箱涵，明挖深基坑、基岩爆破。该方案存在影响现有工程安全和不满足黄河防洪要求等缺点。优化设计方案采用闸后两孔独立衬砌隧洞。方案优化后不但解决了原方案的不利影响，而且经济效益显著，节省预算投资350万余元，占总投资的26.7%。

Abstract:he head sluice is a control project for connecting the Eastern Route of the South to North Water Transfer with the main route of Jiaodong water transfer project,The original project is difficult to be accomplished owing to complicated construction condition by adopting three box culverts.The improved project adopts two tunnels,which not only can solve the disadvantageous influence of the original one,but also save ￥3，500，000（26.7% of total investment）.

Key words:head sluice;improved project;underground excavation;benefit
