木桩围堰在长三角地区水利工程中的应用

The application of timber pile cofferdam in hydraulic engineering in the Changjiang River delta region

通过设计参数对围堰稳定影响的分析,并结合实际阐述了木桩围堰在长三角地区水利工程中的应用,详细介绍了不加覆护围堰及两侧加护围堰的施工要点,从理论上分析了木桩围堰的经济性,同时指出木桩围堰可以减小填筑断面,减少土方填筑量,节约用土,并且保护城市环境,值得推广使用。

Through analyzing the influence of design parameter on the stability of cofferdam, the author illustrates the application of timber pile cofferdam in hydraulic engineering in the Changjiang River delta region combined with practice, introduces construction elements of the cofferdam without coat and support and the cofferdam with support at two sides, analyzes the economical efficiency of timber pile cofferdam from theory, and points out that timber pile cofferdam can reduce filling section, cut down earthmoving filling volume, save soil utilization and protect urban environment, which is worthy to be popularized.
