摘要
论述全站仪结合计算机组成巷道围岩变形,自动量测及分析系统的原理、功能及其开发应用,提出全站仪自由设站3维坐标非接触量测、单站独立坐标测线等围岩变形量测的理论和方法,并建立相应的数学平差模型,使围岩变形非接触监测具有更好的可靠性和精度。通过对全站仪观测数据后处理软件的设计和开发,在机载软件控制下,无需进行对中、量仪高,全站仪可自动完成对目标点的监测,由计算机进行所有的数据处理、回归分析和预报,为巷道施工提供及时的信息反馈。
Illustrating the principles, functions and its application of the system by combining a total-station measurement and a computer for monitoring and analyzing tunnel country rock deformation,this paper presents the new theory and some methods of non-contacting free stations of 3 dimensional coordinate measurement as well as the theory and methods of tunnel country rock deformation of the free station independent coordinate measuring-lines. At the same time their concerning mathematic adjustment models are set up. In this way, the reliability and exactness of the none-touching monitoring over the tunnel country rock deformation can be greatly improved. By observing and processing the post data, the total station software has been development .Under the control of the software on-board,the total station can fulfill all measurements to target points automatically without centering the equipment and measure its height. The monitoring data can be processed the post software of the computer and the regression analysis and forecasting the information of the tunnel country rock deformation can be provided in time for tunnel construction.
