珠海高栏港某工程临时围堰位置方案选取

Site selection of temporary cofferdam of a project in Zhuhai Gaolan port

当工程的建设工期较为紧迫,需考虑先期进行该项目的陆域形成和软基处理工程时,临时围堰位置的确定是设计的关键。通过具体分析珠海某工程得出:临时围堰位置的确定应根据工程地质、后建码头结构方案及软基处理的范围等综合考虑,使其对后续可能的码头水工结构方案均具有适应性,尽可能减少重复建设和再次进行软基处理。

When the construction period of a project is pressing,the land formation and soft foundation of this project is considered constructed before the wharf structure,the chosen of the position of the temporary cofferdam is the key of the design.The conclusion is drawn from a project analysis in Zhuhai that the position of the temporary cofferdam must be determined under the consideration of the geology and the wharf structure follow-up and the range of the soft foundation.It must be adaptable to the possible wharf structure,to reduce repeated construction and foundation treatment as much as possible.
