摘要
针对郑州地铁1号线某运营区间隧道变形管片安全性进行评估探讨。通过三维激光扫描对管片收敛值较大的管环进行全面检测,查明病害情况。通过模拟计算和分析评价管片的承载能力和耐久性,并提出了针对本区间变形管片的评估建议。
This paper discusses the safety assessment of tunnel deformation segment in an operation section of Zhengzhou metro line 1.Through 3D laser scanning,the pipe ring with large segment convergence value is comprehensively detected to find out the disease.Through simulation calculation and analysis,the bearing capacity and durability of the segments are evaluated,and the evaluation suggestions for the deformed segments in this section are put forward.
