基于全站仪的隧道自动化监测

Automatic Tunnel Monitoring Based on Total Station

摘要:

近年来，越来越多的城市地下空间开发邻近既有地铁隧道、公路隧道，需要对既有隧道进行实时的自动化监测。全站仪是一种高效、高精度的三维测量设备，可较为方便的在狭长型分布的地下隧道内组建自动化监测系统。本文主要介绍了基于全站仪的隧道自动化监测技术，探讨了隧道沉降、收敛、水平位移监测的精度与可靠性。从多个工程实例来看，采用高精度的全站仪组建自动化监测系统具有良好的适用性，用于隧道的监测精度较高，可满足实时监测的需要。

Abstract:

Nowadays there are more and more urban underground space development projects which are close to metro tunnel and highway tunnel. It is necessary carry out the real-time automatic monitoring for the existing tunnels. The total station is a kind of 3D measuring equipment with high efficiency and accuracy, which can be easily used as the automatic monitoring system in narrow and long tunnel. The automatic tunnel monitoring technology based on total station is mainly introduced. The precision and reliability to monitor the settlement, convergence and horizontal displacement of tunnel are discussed. According to the multi-engineering examples, it has good applicability to establish the automatic monitoring system with high precision total station, which has the high monitoring precision for the tunnel, and can meet the real-time monitoring need.
