| 摘 要： | 本文介绍了一种计算隧道轴线三维坐标偏差的方法,根据隧道轴线的特点对不同线型进行分析,实现了隧道轴线三维坐标的批量快速计算,为盾构推进过程中偏差的确定以及隧道环片拼装后中心坐标偏移的监测提供了一种实现方法。经工程实践证明,该方法的精度可以达到毫米级。无论在隧道推进现场计算还是在环片后期监测中,都具有很高的应用价值。

| Abstract: | This thesis documents a method to calculate deviation of tunnel line. It is based on tunnel line's character to analyse different linestyle, relize a batch of tunnel line's 3-D coordinate quick calculation. This supply a way for definiteness of tunnel line's deviation during shield construction and monitor of centre coordinate excursion after ring plate's assembly. Engineering practices prove this method measure precision can achieve ~mm. It provides highly utility value in field calculation as well as later moniter. |
