Data on point cloud scanning and ground radar of composite lining in jointly constructed tunnel

The dataset includes the original mining surface profile data collected by the terrestrial laser scanning (TLS) and radar information on backfill quality outside the segmental lining which was obtained by the ground-penetration radar (GPR) detection, which supports the numerical analysis outlined in the article titled “Numerical evaluation of segmental tunnel lining with voids in outside backfill.”本数据集包含两类核心数据：一是由地面激光扫描（terrestrial laser scanning, TLS）采集的矿山地表原始剖面数据；二是由探地雷达（ground-penetration radar, GPR）探测获取的管片衬砌外侧回填质量雷达信息。本数据集可为论文"外侧回填存在空洞的管片隧道衬砌数值评估"（原英文标题：Numerical evaluation of segmental tunnel lining with voids in outside backfill）中阐述的数值分析工作提供支撑。
