摘　　要：针对竖向荷载较小的沉箱码头或护岸结构,提出了一种新型的沉箱插板式结构,以减少沉箱使用量。在传统沉箱两侧预留前后两道插板卡槽,在卡槽内设置插板,通过海测及陆侧的插板把间隔放置的沉箱连接成片,形成连片式结构。结合结构的特点和受力,提出了结构的稳定性和内力计算方法。计算分析表明,该结构混凝土用量较少,总体工程造价较低,适用于承受竖向荷载较小的连片式直立码头或护岸。For caisson gravity wharf or revetment structure with small vertical load,a new type of caisson inserting plate structure was proposed to reduce the usage of caisson.Two vertical grooves were set on the sidewalls on both sides of the typical caisson,and the inserted plates were placed in the slots.The caissons placed at intervals were connected into a whole by the front and rear inserted plates,forming a contiguous structure.Combined with the structural and stress characteristics,a method was presented to calculate the structural stability and internal forces.The calculation and analysis show that compared with the typical caisson structure,the concrete consumption of this new structure is less and the overall project cost is lower.In conclusion,this new structure is suitable for contiguous vertical wharf or revetment that receives small vertical load.
