本文介绍了海洋工程领域深层搅拌技术的一些最新进展。深层搅拌法包括现场土壤处理技术，其中添加粘合材料并与原始土壤混合，以改善其机械性能。本文介绍了采用深层搅拌技术的海上混合钻孔灌注桩。通过对API方法和CPT方法的对比分析，验证了MIDOS桩作为不同地质条件下油气构造基础单元的能力。理论计算仅用于桩尺寸的初步估算，不作为详细设计方法。版权所有© 2014 by ASME
This paper presents some recent technological developments in deep mixing for the offshore sector. Deep mixing methods comprise in-situ soil treatment technologies where binding materials are added and blended with the original soils in order to improve their mechanical properties. The MIxed Drilled Offshore Steel (MIDOS) pile is introduced in this paper, which takes advantage of such deep mixing technologies. The comparison between the API approach and CPT-based methods for the prediction of the pile capacity are provided to validate the capability of the MIDOS pile as a foundational element for oil&gas structures in different geological conditions. The theoretical calculations are intended for initial estimation of pile sizing only and are not intended as a detailed design method.Copyright © 2014 by ASME
