摘　　要：盾构穿越江河大堤往往具有较多的技术风险和难度。该文以青草沙原水过江管工程为实例,阐述了盾构施工对大堤造成沉降的理论分析和全方位的施工控制措施,表明通过系统的控制措施与实时监测相结合,可以很好地控制住大堤的沉降。There are more technical risks and difficulties for the shield to cross the river dykes. As an example of Qingchaosha Raw Water Crossing-river Pipeline Project, the article sets forth the theoretical analysis of shield construction to cause the dyke settlement and all-round construction control measures, which show that the combination of the system control measures with the real-time monitor can excellently control the settlement of dyke.
