This paper presents a physical model study of the feasibility and performance of a monopiled gravity base structure (MGBS) for offshore foundation applications. The research study builds on the current interest in hybrid foundation systems such as monopiled footings. The proposed MGBS is essentially a conventional gravity base structure (GBS) with a projecting monopile or caisson. The system relies on the self-weight of the GBS to drive the projecting monopile into the seabed. Once installed, additional ballast can be added to the GBS, and if necessary installation of the projecting monopile can be enhanced through the use of suction. The test programme has concentrated on the response of the system once installed and has investigated a range of geometries for circular monopiles. The results clearly demonstrate a significant enhancement to lateral resistance offered by the addition of a monopile to a GBS.

侧向荷载作用下自装式单桩重力基础结构性能

本文介绍了用于海上基础应用的单桩重力基础结构 (MGBS) 的可行性和性能的物理模型研究。该研究建立在当前对混合基础系统（例如单桩基础）的兴趣之上。提议的 MGBS 本质上是一个传统的重力基础结构 (GBS)，带有突出的单桩或沉箱。该系统依靠GBS的自重将突出的单桩驱动到海床中。安装后，可以向 GBS 添加额外的镇流器，如有必要，可以通过使用吸力来加强突出单桩的安装。测试程序集中在系统安装后的响应上，并研究了圆形单桩的一系列几何形状。
