打浦路复线隧道明挖施工结合河道填堵技术研究

Technical Study of Dapu Rd.Double Track Tunnel Open-Cut Construction Combined with River Landfill

以上海打浦路隧道复线日晖港内工程为背景,对多种常规清淤方法进行比选,针对工程环境保护要求高等特点,提出了注水吸淤的工法,对清淤的关键施工技术围堰施工和注水吸於展开研究,对填浜产生的工后沉降进行分析并提出地基处理措施,研究结论可供类似工程参考。

With the background of Rihui Port Engineering of Dapu Rd Double Track Tunnel,several usual desilting methods are compared and selected.Taking quite high environment requirement into account,the method of filling water and pumping silt is proposed.Key desilting construction technique—cofferdam construction and filling water and pumping silt are studied.The settlement after backfilling river analyzed,the measure for foundation treatment is proposed.Conclusions would be as a reference for future similar project.
