川藏工程走廊重大冻土工程病害调查数据（2020）

该数据集主要内容为G317和G318国道沿线边坡及路面工程病害调查数据集，通过现场调查获得，调查时间为2020年1月9日-1月19日，2020年8月10日至2020年9月2日。调查对象为川藏北线G317（那曲-甘孜）和川藏南线G318(拉萨-新都桥)。调查的病害类型主要包括冻融诱发的边坡病害及灾害（落石、危岩体及碎屑坡）、路面裂缝类病害、松散类病害、坑槽类病害、路基变形类病害以及冬季的涎流冰病害。采用人工调查的方法，观察各类病害破损情况，按要求详细记录路面各种破坏类型的数量（范围）、破坏程度及所在位置。该数据集可为全面了解川藏工程走廊主要公路工程冻融病害情况及相关研究提供依据。

This dataset primarily contains survey data on slope and pavement engineering distresses along National Highways G317 and G318. It was collected through on-site investigations carried out between January 9 and 19, 2020, and between August 10 and September 2, 2020. The survey targets are the northern Sichuan-Tibet Highway G317 (Naqu – Garze) and the southern Sichuan-Tibet Highway G318 (Lhasa – Xinduqiao). The main surveyed distresses include freeze-thaw induced slope hazards and diseases (falling rocks, dangerous rock masses and debris slopes), pavement crack damage, loose pavement distresses, pothole damage, subgrade deformation damage, as well as winter slurry ice diseases. Manual on-site surveys were employed, with researchers observing all types of disease damages and meticulously recording the quantity (scope), damage severity and exact location of each pavement damage type in accordance with standardized requirements. This dataset can serve as a credible basis for comprehensively understanding the freeze-thaw distress status of major highways within the Sichuan-Tibet engineering corridor and supporting relevant academic research.
