长江下游福姜沙水道航道治理双涧沙守护工程施工管理难点及解决方案

摘要

The Shuangjiansha project engineering of Fujiangsha waterway regulation in the lower Yangtze River is currently the one of the largest investment and the most difficult implementation in single beach regulation projects.The implementation of the project has laid a good foundation for 12.5 m deep waterway extending to Nanjing.Based on the introduction of the engineering design and construction process especially the test and application of new technology this article summarizes the difficulties and solutions in the process of construction management and puts forward a set of feasible method which provides valuable reference for other tidal river channel regulation project.%长江下游福姜沙水道航道治理双涧沙守护工程是目前投资最大的单滩治理工程，同时也是实施难度最大的工程之一，工程的实施为12．5 m深水航道上延至南京打下了良好基础。旨在通过介绍工程设计方案、工程施工过程等，突出施工管理过程中的难点及解决方案、特别是新工艺的试验与应用情况并总结出一套可行的工法，为其他潮汐河段航道治理工程提供有价值的参考。
