大水深厚淤泥地质条件下自升式风电平台插拔桩研究

Research on Plug-in Piles of Jack-up Wind Power Platform under Heavy Water and Deep Silt Geological Conditions

插拔桩是自升式风电平台的重要辅助系统,介绍了自升式风电平台插拔桩系统,逐一列举该系统的常见插拔桩操作,并选取施工项目典型地质进行插拔桩计算、地基回流,判断破坏穿刺,计算承载力、插拔力,获得大水深厚淤泥地质特定海域条件情况下,自升式风电平台插拔桩系统达到良好冲桩效果的关键操作,对最新一代自升式风电平台在特殊海况和地质条件下插拔桩系统设计和操作有指导意义。

The plug-in pile is an important auxiliary system of the jack-up wind power platform.This paper briefly introduces the jack-up wind power platform plug-in and pull-out system,lists the common plug-in and pull-out operations of the system one by one,and selects the typical geology of the construction project for plug-in and pull-out.Pile calculation,foundation backflow,judging damage puncture,calculating bearing capacity,plugging force,and obtaining the key operations for the jack-up wind power platform plugging and plugging system to achieve good pile flushing effect under the conditions of large water and deep silt geological conditions in specific sea areas.The design and operation of the plug-in pile system for the first-generation jack-up wind power platform under special sea conditions and geological conditions has key guiding significance.
