摘　　要：针对周边已建有其他建筑物的船坞工程项目,对在船坞施工过程中能有效保护临近建筑物的坞墙结构形式进行研究。以实际工程为例,采用岩土有限元软件PLAXIS对斜桩承台式坞墙进行数值模拟计算。考虑承台尺寸、桩基斜率等多个影响因素,研究坞墙结构的受力和变形特性,验证了所用新型坞墙结构对临近建筑物的保护作用。For construction of dry docks with other buildings already built around it, a new type of docking wall structure with raking pile platform was researched in this paper for the protection of adjacent buildings.Taking a practical project as an example, PLAXIS software is used to simulate the numerical model of the structure. Key factors such as platform size and slope of raking piles are considered while researching the stress of the dock wall structure.These researches prove that the raking pile platform is availability for protection of adjacent buildings.
