摘要

以渤海湾应用的典型三桩筒型基础为例,通过结构静力分析和拖航稳性分析,推导出结构浮运重量与吃水对应关系,为结构设计和浮运施工方案提供理论依据。现场施工证明了计算分析的正确性,并对渤海近年该典型结构海上成功应用实例进行介绍,以期开阔工程技术人员海上简易平台设计思路,为极浅海海洋工程技术提供有益参考。

Abstract

Abstract:Taking the typical three-suction pipe foundation applied in Bohai Bay as an ex ample, its structure towing stability, and foundation stability was calculated and analyzed.Based on it, the correspondence relationship between structure's floating weight and draft was derived, and provided a theoretical basis for the structural design and construction plan of floating.Meanwhile, the successful application instances of this typical structure in Bohai Bay in recent years are introduced in order to expand design ideas of minimum platforms and provide useful information for the application of offshore engineering technology in extreme shallow water.
