沿海复杂地质区嵌岩桩施工工艺

Construction technology of rock-socketed piles in coastal area of complicated geologic condition

以洋山深水港区钢管桩码头工程为例,对沿海复杂地质区嵌岩桩施工难点——海上施工平台搭设、冲孔吊打和钢桩焊接工艺进行分析,并提出对策,为沿海复杂地区嵌岩桩实施提供了安全、可靠、简便及节约资源的施工方法。

Taking Yangshan deepwater port steel-pipe piled wharf engineering for example, this paper probes into the construction difficulties of rock-socketed piles in the coastal area of complicated geologic conditions, i.e., setting up of the offshore construction platform, punching and lifting and steel pile welding, and puts forward countermeasures to provide a safe, reliable, convenient and energy-saving construction method for the construction of the rock-socketed pile in the coastal area with complicated geologic conditions.
