双排钻孔灌注桩坞墙结构设计

摘要

结合浙江某船厂船坞改扩建工程可利用岸线和空间极其有限、地质条件复杂、施工条件局限等特点，提出了一种双排钻孔灌注桩坞墙结构。在分析其作用机理和计算方法的基础上，给出了一种基于m法的数值模拟方法，并对该结构进行了详细的受力分析，为本工程提供了可靠的结构设计依据。%Considering that the shipyard dock renovation and expansion project of Zhejiang is characterized by extremely limited shoreline and space, complicated geologic conditions, confined construction conditions, we propose a dock wall structure, i.e. double-wall bored pile dock wall structure. Based on the analysis of the mechanism and calculation methods, this paper gives a numerical simulation method and detailed stress analysis for the new structure, which provides reference for similar projects.
