摘　　要：根据长江口深水航道治理工程北导堤堤头部位2.6km长软基段的工程条件,开发了一种新型的空心方块斜坡堤结构。这种新型结构的基本构思是利用各空心方块之间以及空心方块本身的两个空隙率,降低堤身单位体积的重量以及堤身断面总重量,从而满足软土地基的承载力和整体稳定的要求。对空心方块斜坡堤的设计、试验研究以及工程实施效果等作概要介绍。A new structure type of hollow-block mound breakwater was developed according to the soft soil conditions of a 2.6 km long jetty segment close to the head of the north estuary jetty of the deepwater channel regulation project at the Yangtze Estuary. The basic conception of this new structure is to utilize the porosity among the hollow blocks as well as the voids inside the blocks to reduce the unit and total weight of the mound, so as to satisfy the requirements of the bearing capacity and the stability of soft soil foundation. The design, experimental study and effect of engineering execution of the hollow-block mound breakwater are outlined in the paper.
