上海地区拥有将近500km的海塘,由于工程需要,经常会出现对海塘进行开缺破拆的需求,部分工程需要建设临时围堰。对于在非汛期内可完成的工程需要利用非汛期的水文条件进行围堰高程设计。本文以金山地区岸线为例,计算了不同重现期的非汛期水文条件下不同型式围堰断面在不同滩地高程的围堰设计高程,并进行了比较,研究成果可为将来的工程应用提供借鉴。
In Shanghai, there are nearly 500km seawalls. Due to the project needs, there is a frequent need for opening and breaking the seawalls. Some of the projects require temporary cofferdam construction. For projects that can be completed in non-flood season, we need to use cofferdam elevation design in non-flood season hydrological conditions. Taking the shoreline of Jinshan area as an example, the design elevation of cofferdam with different types of cofferdam sections under different floodplain hydrological conditions is calculated and compared with each other. The results of the research can be used for future engineering applications Learn from
