带翼板沉箱在直立式码头结构中的应用

带翼板沉箱作为新型沉箱结构，与常规沉箱码头结构相比，可有效改善码头前波浪反射情况、减小墙后土压力、降低工程投资，采用类似结构的梳式防波堤已有实际工程案例，但是，目前带翼板沉箱在后方有回填土的直立式码头中使用较少。介绍了带翼板沉箱结构在大连松木岛件杂货码头中的应用，分析波浪以及墙后填土对梳式码头结构的作用，对沉箱翼板尺度的选取进行研究，为此类新型结构的应用提供参考。

Applications of caisson with flange slab in vertical pier structure

Compared with the conventional caisson pier structure,a new type caisson with flange slab can effectively improve the wave reflection,decrease earth pressure behind the wall,and reduce the engineering investment.There are some practical engineering cases in comb-type breakwater while the caisson with flange slab is rarely used in vertical pier structure which has backfill in the rear.This paper introduces the application of caisson with flange slab in Dalian Songmu island general cargo pier,analyzes the effect of wave and wall backfill on comb-type pier structure,and studies the selection of flange slab caisson scale.
