以上海浦东污水治理二期 Ｓ Ｂ 泵站大型沉井为工程背景， 通过建立 Ｐ Ｈ Ｏ Ｔ Ｏ 数字化摄影测量解析系统， 首次将近景化摄影测量方法实用于大型沉井施工全过程的位移监测。在 Ａｕｔｏ Ｃ Ａ Ｄ 及 Ｍａｔｌａｂ５ ．０ 软件系统环境下实现位移、偏斜、下沉及沉井三维工况等信息的图文动态显示、输出及量测信息的多部门、多终端共享。监测结果为沉井施工现场所采用， 达到了防偏纠偏、及时改善后续工程施工方法、保证沉井稳定下沉的目的。为今后实施沉井施工过程自动化实时监测提供可鉴之处。
Based on the engineering background of the large open caisson of Shanghai Pudong Sewage Treatment Phase II S B pumping station, the digital photogrammetry and analysis system of P H O T O was established. For the first time, the close-range photogrammetry method was applied to the displacement monitoring of the large-scale open caisson construction process for the first time. In Auto C A D and Matlab5. 0 Multi-sector and multi-terminal sharing of graphic dynamic display, output, and measurement information for information such as displacement, skew, sinking, and sinking wells in the software system environment. The monitoring results are adopted by the caisson construction site to achieve the purpose of preventing deviations, correcting the follow-up construction methods in time, and ensuring that the caisson sinks steadily. For the future implementation of automated caisson construction process real-time monitoring provides a place for Kam.
