摘要
提出了一种利用全站仪进行地下水封石洞库容量校准的新方法,通过对洞库各个组成部分进行导线布置,形成统一的坐标系统,并对各部分进行数据采集和数据拟合,最终得出洞库的容量表及曲线图。通过建立测量模型,分析引入的各个不确定度分量,得出校准方法不确定度满足相关规范的技术要求。结果表明:洞库校准方法的相对扩展不确定度为4×10^(-3),包含因子k=2,置信概率P=95%。
A capacity calibration method of underground water-sealed storage in rock caverns using total station was proposed,which arranged traverse surveying of each part of the cavern,formed a unified coordinate system,and the capacity table and curves of the cave are finally obtained by data acquisition and data fitted of the cavern.By establishing the measurement model and analyzing the uncertainty components,the uncertainty of the calibration method meeted the technical requirements of relevant specifications.The results showed that the relative expanded uncertainty was 4‰,when coverage factor k=2,confidence probability P=95%.
