- 摘要:
- 以渤海某海洋平台为例,通过对该平台桩基承载力的检测,分析得出该平台承载力未达到设计值,故对该平台桩基进行了为期一年的沉降监测,在监测中,使用了适合海洋平台长期监测的光纤光栅技术。监测结果表明,平台的关键部位没有发生倾角的变化,因此判断桩基础没有发生不均匀沉降,此平台是安全的。建议在今后的使用过程中,平台使用方应继续按照桩基监测报警戒线的要求执行,不能随意增加上部荷载,同时必须严格控制活荷载,以保证平台桩基的安全。
The pile foundation bearing capacity of an offshore platform in Bohai Bay was inspected and it was found that the bearing capacity of this platform was under the design value.Hence,a one-year settlement monitoring for the platform was carried out by using optical fiber gratings suitable for long period monitoring of offshore platform.The result indicated that there was no change in platform obliquity,thus the uneven settlement of the pile foundation did not happen and the platform was safe.It is suggested that the platform application henceforth should continuously be in accordance with the alarm conditions of the pile foundation monitoring,the upper loads on the platform should not increase at discretion and the active loads must be strictly controlled so as to ensure safety of the pile foundation.2012,05(05): 17-20 收稿日期：2011-8-5分类号：P75;TU476作者简介：王圣强（1981- ），男，山东梁山人，工程师，2008年毕业于天津大学，获得岩土工程硕士学位，现主要从事海洋平台陆地建造及海上安装工作。参考文献：
