摘要
海洋工程桩基施工中经常会遇到各种技术问题,为此引入高应变动力检测技术来监测桩基施工过程。结合东海丽水36-1气田开发项目导管架桩基安装中进行的水下高应变动力检测试验成功案例,对桩基水下动测试验步骤进行了详细的介绍和讨论,对水下高应变动力检测试验的特点进行了总结,并对现场数据利用CAPWAP技术进行了分析。现场监测数据分析结果表明,高应变动力检测技术适用于海洋工程水下桩基监测以及桩基承载力的评估。
Offshore jacket platform foundation engineering is regarded as the most important and difficult content in offshore platform construction, therefore, the quality in detection of pile foundation is particularly critical. High strain dynamic test has been applied to dynamically monitoring the installation of underwater foundation pile in a developing project of Li Sui gas field in the East China Sea. This is the first test in China and is very challenging for application of this technique to underwater piling. Test procedure and characteristics are discussed and summarized. Field data are analyzed with software CAPWAP. According to the results from CAPWAP analysis, the pile integrity is good.
