摘要
用常规导线测量和陀螺测量2种方法对提高隧道贯通精度的效果显著性进行了分析,提出可通过增加导线边长和加测陀螺边的方法提高隧道的贯通精度,并运用了2种方法对隧道贯通精度提升的理论计算对比研究,并依托某地铁8号线工程进行了实际验证,隧道贯通精度提升效果明显,且一定程度上解决了隧道延伸前段最弱边横向摆动问题。
The two methods of conventional traverse measurement and gyro measurement are used to analyze the significance of the effect of improving the tunnel penetration accuracy.It is proposed that the tunnel penetration accuracy can be improved by increasing the wire side length and measuring the gyro edge.A comparative study of theoretical calculations on the improvement of tunnel penetration accuracy,and actual verification based on a Metro Line 8 project,shows that the tunnel penetration accuracy is improved significantly,and to a certain extent the problem of the weakest side lateral swing in the front section of the tunnel extension is solved.
