浅埋暗挖隧道收敛测量的误差分析
Error Analysis of Shallow Tunnel Convergence Measurement
【摘要】 推导了浅埋暗挖隧道收敛测量极限误差的计算公式,建立了判断异常收敛数据的公式。通过实测数据取样分析,得出浅埋暗挖隧道收敛极限误差的经验值。最后利用EXCEL对实测数据中添加异常收敛数据警告条件,以方便测量人员及时有效地找出异常数据、判断隧道收敛状况。
【Abstract】 The formula for computing the limit error of the convergence measurement in shallow tunnel and the formula for judging abnormal data have been established.Some experiential data were gained from the analysis of a real tunnel convergence measurement.Finally the author use EXCEL to cope with the data by adding a warning condition.This provides an instinct and effective way to judge the convergence state of tunnel.
