摘要
为探寻临海区域承台施工，水位高差常年受海水潮汐影响，水中承台桩顶标高在水下标高 0.7 米，且不着河底，距河底最大深处达 3.5 米。承台位于河道主通航孔附近，为便于通航不可采用填土筑岛围堰工法。本工法设计理念为将充分利用钢管桩与钢套箱合体承受水压力，同时利用管井降水改变承台围堰处的水流路径，确保承台无水施工。
Abstract
In order to explore the abutment construction in the offshore area，the water level height difference is affected by the seawater tide allyear round.The elevation of the abutment pile in the water is 0.7 meters above the water level，and it does not reach the bottom of the river，which is 3.5meters away from the maximum depth of the river bottom.The bearing platform is located near the main navigation hole of the channel.The designconcept of this work method is to make full use of the combination of steel pipe pile and steel casing to withstand water pressure，and at the sametime change the water flow path at the cofferdam of the bearing platform by using the pipe well precipitation to ensure the construction of the bearingplatform without water.
