强浪条件下振冲碎石桩施工工艺

以以色列阿什杜德港项目为背景,介绍了海上振冲碎石桩的施工工艺,结合实际施工工效对施工工艺进行评估,并分析了强浪条件对碎石桩施工定位偏差及施工工效的影响。在外海地区,波浪条件恶劣,传统的振冲碎石桩施工工艺,即方驳搭载振冲设备的施工工效偏低、作业窗口有限,并且施工精度不高。为寻求有效克服强浪条件影响的大面积海上振冲碎石桩施工方法,提出采用碎石桩施工专用顶升平台的解决方案。

Stone column offshore construction under strong wave condition

Based on the construction of Hadarom port at Ashdod,Israel,this paper generally introduces the method of stone column offshore construction with the actual work efficiency,and analyzes the influence of strong wave condition on position deviation control and work efficiency.Due to the bad wave condition in open water,the traditional construction method as the vibration equipment installed on the barge can hardly meet the milestone requirement of large-scale construction,which is low work efficiency,limits operation window time,and is low construction precision.In order to overcome the wave condition influence and solve the work efficiency problem,we propose a solution as the self-elevating platform(Jack-Up)for stone column offshore construction.
