全自动监测系统在大型沉井工程中的开发与应用

Automatic Monitoring System in Large-scale Open Caisson Project:Development and Application

大型沉井工程周边往往存在较多建筑物、构筑物,为了更好地控制沉井对周边影响,沉井过程中需要进行实时监测,传统的人工测量效率低且夜间测量效果不佳,为此开发一套沉井全自动监测系统,可对沉井姿态实时测量。结果表明,全自动监测系统可在数十天的过程中稳定运行,对沉井进行高精度的实时监测,针对实际工程提供实时高程、位移数据,为沉井下沉过程中提供准确的纠偏数据,以便达到良好的就位精度。

There are often many buildings and structures around large-scale open caisson projects.In order to better control the influence of open caisson on the periphery,real-time monitoring is needed in the process of open caisson.The traditional manual measurement efficiency is low and the night measurement effect is not good.For this reason,a set of fully automatic monitoring system for open caisson is developed,which can measure the posture of open caisson in real time.The results show that the automatic monitoring system can run stably in the process of tens of days,carry out high-precision real-time monitoring of open caisson,provide real-time elevation and displacement data for practical engineering,and provide accurate deviation correction data for the process of caisson sinking,in order to achieve good positioning accuracy.
