环境因素对测量塔全站仪定位精度的影响研究

Study on Impact of Environmental Factors on Measurement of Total-station Positioning

系统给出了影响测量塔全站仪定位精度的温度、湿度、气压气象因素对测量定位影响的模型,并借助仿真实验,理论上给出了确保施工中测量定位精度的温度和气压参数;分析了波浪因素对测量定位的影响,并以实际施工作业中常采用的Leica TCA 2003全站仪动态跟踪速度为参考,给出风力和浪高等极限参数。论文研究对实际施工具有较强的指导作用。

This paper systematically gives out the influence models of temperature, humidity and barometric pressure meteo- rological factors on the positioning accuracy of Total Station observation in measurement-tower pipe construction. Based on the models, the parameters of temperature and barometric pressure, which is used to ensure measurement accuracy in theory, are proposed by means of simulation experiments. The impact of wave on measurement positioning is analyzed, and these limit parameters of wind and wave height in actual applications are given out by refereeing the dynamic tracking speed of Leica TCA 2003 Total Station. The conclusions achieved by the research have the guidance for actual projects.
