导管架钢桩溜桩后桩基承载力评估方法及应用研究

导管架钢桩溜桩给海上施工带来很大风险,也让人们对平台运行后的桩基承栽力产生了担忧。为了保证平台服役期间的安全,以东海某导管架溜桩后的桩基承载力评估为例,根据实际打桩情况,提出导管架桩基承载力后评估方法,并进行分析研究,以期为今后类似导管架在打桩过程中出现溜桩后桩基承载力的后评估提供借鉴。

Evaluation Method and Application Study on the Loading Capacity of the Pile Foundation after the Slip Pile

Jacket slip pile might bring significant risk to the offshore construction, and make people worrying about the loading capability of piles after operation of platform. In order to ensure safety during operation of platform, by evaluation on the loading capacity of a jacket slide pile after pile in East China Sea as an example, a post evaluation method on the loading capacity of pile supported jacket has been put forward according to the actual piling conditions, which can provide reference for similar future post evaluation on the loading capacity of pile slip during piling process.
