大型沉井数字化监测与控制系统的试验研究

结合上海市污水治理二期工程中最大的沉井施工项目ＳＢ泵站沉井工程 ,采用数码相机近景摄影对沉井下沉过程中各方向平移、偏斜及扭转的时间历程进行数字化监测。并运用现代控制理论对沉井的下沉量、下沉速度、井体偏斜量作出预估并结合实测结果对沉井的下沉过程进行动态优化 ,按期望目标进行在线控制 ,并对抗井的终沉进社分析与预报以便达到稳步下沉。

Study and Tests on Digital Monitoring and Control System in Large Caisson

The digital camera is used to take close shoots for digital monitoring of the timed horizontal movement, inclining and twisting of a sinking caisson. Advanced theories are adopted to control the sinking volume and speed and forecast the deviation of the caisson body so that the sinking process can be optimized dynamically and brought under an on line control to reach the expected position. It is also possible to analyze and forecast the final sinking and ensure steady sinking.;
