摘　　要：沉井基础具有良好的稳定性和整体性,但在施工过程中容易引发沉井倾斜等质量事故,本文根据某矩形沉井基础施工实例,介绍了沉井施工的基本流程,详细分析了沉井质量控制的关键环节,重点对沉井挖土下沉与沉井纠偏技术进行了分析,可供类似工程参考。The open caisson foundation has good stability and integrity, but it is easy to cause quality accidents such as sinking of the open caisson during construction. This article introduces the basic process of open caisson construction based on a rectangular open caisson foundation construction example, analyzes the key links of open caisson quality control in detail, and focuses on the analysis of open caisson excavation subsidence and open caisson deviation correction technology, which can provide reference for similar projects.
