【摘要】 地铁隧道的全面和持续的形变监测是确保地铁运行安全性的重要组成部分。通常的形变监测方法,如测量管道的水平偏移或沉降,对于长距离隧道的区段,无法在实时性和隧道形变趋势分析方面满足运营安全监测的需求。双车行进激光偏移累积监测通过对双车的行进距离进行准确测量。基准点坐标与自动水平可见激光偏移测量的联合应用有效获取到隧道的轴向偏移及形变趋势。这种新的隧道形变监测方法,能有效地满足地铁运营安全监测的需求,特别是对于长距离隧道的监测,它不仅能提供隧道整体形变实时性的数据,还能进行隧道整体准确的形变趋势分析,从而提高地铁运营的安全性。更多还原

【Abstract】 Comprehensive and continuous deformation monitoring of subway tunnels is a critical component in ensuring the safety of subway operations. Traditional deformation monitoring methods, such as measuring the horizontal displacement or settlement of the tunnel, cannot meet the requirements of operational safety monitoring in terms of real-time response and tunnel deformation trend analysis, particularly for long-distance tunnel sections. The new method of monitoring tunnel deformation by cumulative offset measurement using twin vehicle-laser displacement offers a solution. By accurately measuring the travel distance of the twin vehicle and combining it with baseline point coordinates and automatic horizontal visible laser offset measurements, it effectively captures axial displacement and deformation trends in the tunnel. This new tunnel deformation monitoring method effectively meets the needs of subway operational safety monitoring, especially for long-distance tunnel monitoring. It not only provides real-time data on overall tunnel deformation but also enables accurate analysis of overall tunnel deformation trends, thereby enhancing the safety of subway operations.更多还原
