格尔木-那曲、共玉、中尼雅万流域高等级公路沿线路基变形（2021-2024）

青藏公路5个断面共计20变形测点海拔高度数据，青藏铁路5个断面共计12个变形测点海拔高程数据。青藏公路沿线路基变形的每个监测场地共有 4 个横向剖面，每个横向剖面布置了 5 个监测点，分别设置在左右路肩、路肩和路基中心之间中间、路基中心处。每个路基变形观测场地共有变形监测控制点20个。每个路基变形的监测路段专门设有16 m 深的水准参考点一个。青藏铁路沿线路基变形设置了4个横向剖面，每个横向剖面布置了3个监测点，分别设置在左右路肩和路基中心混凝土轨枕上。每个路基变形观测场共有变形监测控制点12个。每个路基变形的监测路段专门设置16m深的水准参考点一个。青藏铁路和公路的路基变形测量是采用水准仪进行测量。精度为±0.1mm。变形测试控制主要是每次测量后的数据与前一次测量数据的比对、审核和复查。

This dataset includes elevation data of 20 deformation monitoring points across 5 sections of the Qinghai-Tibet Highway, and elevation data of 12 deformation monitoring points across 5 sections of the Qinghai-Tibet Railway. For each subgrade deformation monitoring site along the Qinghai-Tibet Highway, 4 transverse profiles are configured, with 5 monitoring points deployed on each transverse profile, which are respectively located at the left road shoulder, right road shoulder, the midpoint between the road shoulder and subgrade center, and the subgrade center. Each subgrade deformation observation site has a total of 20 deformation monitoring control points. A dedicated 16-meter-deep leveling reference point is established for each monitoring section of subgrade deformation on the Qinghai-Tibet Highway. For subgrade deformation monitoring along the Qinghai-Tibet Railway, 4 transverse profiles are arranged, with 3 monitoring points installed on each transverse profile, which are respectively located on the left road shoulder, right road shoulder, and the concrete sleeper at the subgrade center. Each subgrade deformation observation site has a total of 12 deformation monitoring control points. A dedicated 16-meter-deep leveling reference point is established for each monitoring section of subgrade deformation on the Qinghai-Tibet Railway. Subgrade deformation measurements for both the Qinghai-Tibet Highway and Railway are carried out using leveling instruments, with an accuracy of ±0.1 mm. Deformation test control primarily involves comparing, reviewing, and rechecking the data obtained from each measurement with that of the preceding measurement.
