南亚通道及喜马拉雅山重大冻土工程病害调查数据（2020-2021）

该数据集主要内容为青藏公路G109、青藏铁路以及新藏公路G219国道沿线地质灾害、路面病害以及桥涵病害调查数据集，调查时间为2020年8月12日--2020年8月19日，2021年7月26日--2021年8月15日。调查对象为南亚通道及喜马拉雅山区工程。调查的病害类型主要包括冻融诱发的地质灾害（落石、危岩体、泥石流冲沟及碎屑坡）、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桥涵病害等等。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、桥涵以及地质灾害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南亚通道及喜马拉雅山区工程冻融病害情况及相关研究提供依据。

This dataset primarily contains survey data on geological hazards, pavement diseases and bridge and culvert diseases along the Qinghai-Tibet Highway G109, the Qinghai-Tibet Railway and the Xinjiang-Tibet National Highway G219. The surveys were conducted in two phases: August 12 – August 19, 2020, and July 26 – August 15, 2021. The survey targets are the engineering projects along the South Asia Corridor and in the Himalayan region. The main surveyed disease types include freeze-thaw induced geological hazards (falling rocks, dangerous rock masses, debris flow gullies and debris slopes), pavement crack-related diseases, loose pavement diseases, pothole diseases, subgrade deformation diseases, bridge and culvert diseases, etc. Manual investigation was adopted, where the damage status of various diseases was observed, and the quantity (scope), damage degree and location of all damage types of pavements, bridges and culverts, as well as geological hazards were recorded in detail as required. This dataset can provide a basis for comprehensively understanding the freeze-thaw disease status of projects in the South Asia Corridor and the Himalayan region and carrying out relevant research.
