该数据集对2014年3月至2017年11月间青藏公路区间K2900~K3400段内的路基裂缝破坏情况进行了多次实地调查，调查内容包括路基高度、道路方向、裂缝的宽度和长度、路基融化沉降等，对调查进行归纳总结分析得出了青藏公路路基裂缝的分布特征。主要分析了道路的走向、最大路基裂缝宽度以及路面沉降差，发现在靠近唐古拉山区的K3330断面，裂缝最大宽度达到37 cm。", "ds_source": "

This data set has carried out many field investigations on the subgrade crack damage in the section K2900~K3400 of the Qinghai Tibet Highway from March 2014 to November 2017. The investigation contents include subgrade height, road direction, crack width and length, subgrade melting settlement, etc. The distribution characteristics of subgrade cracks of the Qinghai Tibet Highway are obtained through the summary and analysis of the investigation. The trend of the road, the maximum width of the subgrade crack and the differential settlement of the pavement are mainly analyzed. It is found that the maximum width of the crack reaches 37 cm at the K3330 section near the Tanggula mountain area.
