建造于陡坡的坞首围堰设计与施工方案优化

Optimization of Design and Construction Plan for Dock Conferrdam Built on Steep Bank

鼎衡船坞工程围堰位于长江岸侧陡坡、深水区域,围堰内侧深达十几米的坞首结构施工基坑对围堰的稳定影响较大。通过对围堰设计与施工的研究,对结构设计与施工进行优化、创新,结合工程现场条件,制定出合理的最优施工方案,解决影响岸坡稳定的各种因素。

The conferrdam of the Dingheng dock project is located in the deep water of the steep bank of the Yangtze River. The foundation pit of the dock project, which is more than ten meters deep, may have negative effect on the safety and solidity of the eonferream. The paper studies and optimizes the design and construction of the conferream. The paper studies and optimizes the design and construction of the conferrdam and makes the most optimized construction plan according to the construction condition on the spot to get rid of all the factors which may threaten the safety of the conferrdam.
