摘要
安庆长江公路大桥南北主塔墩均采用钢围堰施工,确定钢围堰的底标高难度较大,主要的确定因素一是选择合适 的开口时间,二是应充分考虑水文与冲刷的影响,三是要考虑工程地质情况及施工单位的机具设备情况。
The north and south main tower of An'qing Yangzi River highway bridge are made by the steel-cofferdam. As it's difficulty to make sure the high of cofferdam. The main factor should make sure the time of opening. Then, it should be consider the influence of hydrology and scour. The others it should be consider the geology in construction area and construction equipment.
