摘要
介绍了泰州长江大桥南锚碇沉井基础的施工特点和下沉阻力现场监测技术。在下沉过程中,采用土压力计监测了每节沉井的侧壁土压力和沉井的刃脚土压力。通过这些监测数据的整理和规律分析,既控制了沉井的安全平稳的下沉,也为同类型的大型沉井的设计和施工提供了可以参考的依据。
The monitoring technique of sinking resistance for the south anchor caisson foundation of the Taizhou Yangtze Highway Bridge. During sinking of the caisson, the earth pressure cells were used to test the side resistance and tip resistance of the caisson. From these monitoring data collation and analysis, they will be helpful for the safe sinking of the large caisson and ensured smooth completion of the project. They will be valuable for the monitoring and construction of the large caisson in the similar project.
