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。 Based on the project of Rihui harbor inside Dapu Road Tunnel in Shanghai, a variety of conventional dredging methods were compared and selected. According to the high requirements of engineering environmental protection, a method of water injection and siltation was proposed, and the key construction technology of cofferdam Construction and water injection Suction In the study, the post-construction settlement of Yam-hanbang was analyzed and measures for foundation treatment were proposed. The conclusions of the study can be used for reference to similar projects.
