针对长江口N IIC-1区段特殊的工况和地质条件,采用了创新的空心方块斜坡堤结构。在满足抗浪稳定性要求的同时,利用空心块体自身及块体间的大空隙率减轻堤身自重应力,满足了地基承载力和堤身整体稳定性要求。开发了空心方块斜坡堤结构全套施工工艺。该堤段工程已顺利建成,并经受了台风浪的考验,使用效果良好。文章对这一新型结构诞生的背景、创新思路、开发及实践过程和工程效果作了简要介绍。

In view of the special working conditions and geological conditions in Section NIIC-1 of the Changjiang Estuary,the innovative structure of mound breakwaters of hollow cubic blocks were adopted.While meeting the requirements for wave resistance,the porosity of the hollow cubic blocks and the voids inside the blocks were used to reduce the self-weight stress of the breakwaters,thus satisfying the requirements for the bearing capacity of the foundations and the integral stability of the breakwaters.A complete set of technology has been developed for the construction of the mound breakwater stucture of hollow cubic blocks.The section of the breakwaters has been successfully completed and came through the ordeal of typhoons without failure,proving favorable engineering effect.The paper presents a brief introduction to the background of development of the innovative structure,the concept of innovation,the process of development and practice as well as the engineering results.
