摘　　要：沿海/江发电厂循环水取排水盾构施工工艺的最大难点是掘进施工需穿越防汛大堤,如控制不好会造成防汛大堤局部沉降。根据上海某电厂2×1000MW机组循环水取排水工程的特点,制定了盾构法隧道施工穿越海防大堤的沉降控制措施,有效地控制了大堤沉降。The most difficult point of the power plant across sea/river circulating water taking catchment engineering shield construction craft is that excavation construction needs to cross the defense dike,which can cause partly dike subsidence without proper control.Based on the characteristics of the circulating water draining engineering from one 2×1000 MW unit in a power plant in Shanghai,the subsidence control measures by the shield construction method was drawn up,which can control the subsidence of dike effectively.
