复杂地质和环境条件下水闸围堰工程设计技术

在河流中建设水闸、船闸,其围堰工程是保证主体工程安全干施工的重要前提和保障。结合某水闸工程设计,针对围堰设计遇到的地质和环境条件复杂、施工场地狭窄、施工期不断流等难题,开展围堰总体布置、纵横向围堰结构设计、支护围堰结构设计、围堰止水墙设计等一系列关键技术问题研究。采用研究成果设计的方案不仅可以减少围堰工程量、节约工期,而且能确保项目顺利安全实施。

Lock cofferdam engineering design under complicated geologic and environmental conditions

The cofferdam project plays an important role for the protection and safe construction of the main project when the shiplock is constructed in the river.Combining with the design of a lock project,we carry out a research on a series of key technologies including the general arrangement and structural design of cofferdam in view of problems such as the complicated geological and environmental conditions,narrow construction site,etc.By the design scheme based on the research,we can not only decrease the cofferdam engineering volume and shorten the construction period,but also guarantee the safe and smooth implementation of the project.
