摘　　要：本文依托“长江南京以下12.5m深水航道二期工程”,创新性地设计了新型砂肋软体排替代高滩区传统联锁块软体排加块石压护结构。新结构因地制宜,即能满足保砂固土的功能性要求,又可以充分利用工程区砂源相对丰富的特点降低工程造价,充分体现出工程的生态环保设计理念。通过本文的研究,为内河航道整治高滩护底提供了一种全新的结构型式,也为类似工程项目提供了参考经验。Based on the second phase of the 12.5-meter deepwater waterway project under Nanjing of the Yangtze River, this paper innovatively designs a new type of sand rib soft mattress to replace the traditional interlocking block soft mattress and block stone pressure protection structure in high beach area. The new structure can not only meet the functional requirements of sand conservation and soil consolidation, but also make full use of the relatively rich sand sources in the project area to reduce the project cost, which fully reflects the ecological environmental protection design concept of the project. Through the research of this paper, it provides a new structure form for the regulation of high beach and bottom protection of inland waterway, and also provides reference experience for similar projects.
