Research on the Construction of Tunnel Monitoring Measurement and Safety Step Information System
In line with the management requirements of group-level construction enterprises for tunnel monitoring and measurement and safety distance,this paper systematically studies the monitoring and measurement data from multiple aspects,including data collection,uploading,analysis,early warning,and report output and develops monitoring and measurement and safety step management information system which is fully applied to the high-risk tunnel management and control.The system organically integrates monitoring and measurement,safety step data collection and calculation in one.The coordinate inverse calculation program supports inverse calculation of various types of lines,including straight lines,circular curves,easement curves,and chain breaks.The acquisition terminal directly controls the total station to measure the coordinates and inversely calculate the safety step data,simultaneously improving the speediness of safety step data collection and the accuracy of calculations.
