上海某感潮航道整治工程围堰施工技术

为有效解决位于长江三角洲冲积平原的感潮航道在升级改造期间,其护岸结构作业面应干地施工以及经济合理地控制工程造价的要求,以杭申线(上海段)航道整治工程为例,在深入勘查施工现场的水文与地质工况后,结合工程地质勘探资料,提出常规型、加固型和补强型等三种围堰施工方法,并就其稳定与安全性进行了理论分析与优化。在围堰施工期间,对若干施工关键控制点提出了相应注意事项。实践证明该施工技术满足感潮航道整治工程护岸结构施工的安全与防护要求,且经济效益好。

COFFERDAM CONSTRUCTION TECHNOLOGY FOR TIDAL WATERWAY REGULATION PROJECT IN SHANGHAI

During the upgrade path of the tidal waterway in the Yangtze River Delta Plain, to effectively solve the construction needs of the revetment structure of dry land work space, as well as economic rationality requirements to control project cost. Article to Hang-shen （Shanghai Section） Waterway Regulation Project, for example, an in-depth exploration at the construction site of the hydrological and geological conditions, the combination of engineering geological exploration data, made three kinds of cofferdam construction methods that conventional type, reinforcement type and enhance type, and on its stability and security of theoretical analysis and optimization. During the construction period, we put forward a corresponding note to several key points. Practice has proved that the methods to meet the safety and protection requirements of the bank revetment project construction, and it＇s economic is better.
