摘　　要：通过黄石长江公路大桥主墩钢围堰下沉模拟实验,论述了钢围堰下沉不同阶段,特别是即将着床时钢围堰附近的流速、流态和河床冲淤情况及主要锚缆受力工况,提出了钢围堰下沉时的施工要点。Based on settlement simulation test for the steel cofferdam of Huangshi Yangtze River Bridge main pier, this paper expounds the conditions of flow velocity, flow pattern, scour && deposition of riverbed and pulling force of anchor chain system around steel cofferdam when steel cofferdam sink in water, especially near to river bed, based on which, essentials for steel cofferdam sinking construction are put forward.
