摘　　要：根据实际工程需要,提出了一种适宜建造在软土地基上的新的空心方块斜坡堤型式。这种新型结构是利用各空心方块之间以及空心方块本身的空隙,降低堤身单位体积的重量以及堤身断面总重量,从而满足软土地基承载力和整体稳定的要求。结合长江口深水航道治理工程的北导堤堤头部位2.6km长的软基段,对空心方块斜坡堤的设计和试验研究情况作概要介绍。　 A new type of hollow-block mound breakwater suitable to be built on soft soil foundation is proposed according to the practical engineering demand. The basic conception of this new structure is to utilize the porosity among the hollow blocks as well as the voids inside the blocks in order to reduce the unit and the total weights of the mound to satisfy the requirement of the bearing capacity and the stability of the soft foundation.　The design and experimental study of the hollow-block mound breakwater are introduced generally for a segment of the north jetty, with a length of 2.6 km close to the jetty head, situated on very soft muddy soil of the Deep Water Channel Improvement Project at the Yangtze River estuary.
