三江源（共玉高速公路）工程病害调查数据（2020）

该数据集主要内容为共玉高速公路路面病害调查数据集，调查时间为2020年7月26日-2020年8月7日，调查对象为共玉高速公路。调查的病害类型主要包括不均匀沉陷、路面波浪和横纵向裂缝病害等。采用人工调查的方法，现场测量并记录共玉高速公路多年冻土区路段（鄂拉山-清水河）各类病害类型及发育情况，按要求详细记录共玉高速公路路面各种破坏类型的数量、长度、病害所在位置（经纬度）等。其中，高程参考系统采用1985国家高程基准，经纬度采用CGCS2000坐标系统。该数据集可为了解共玉高速公路工程冻融病害情况及相关研究提供依据。

This dataset primarily comprises pavement distress survey data for the Gongyu Expressway. The survey was conducted between July 26 and August 7, 2020, targeting the Gongyu Expressway as the survey subject. The main surveyed distress types include uneven settlement, pavement corrugation, transverse and longitudinal cracks, and other common pavement damages. Artificial survey methods were adopted to measure and document the types and development status of various distresses in the permafrost section (Elashan-Qingshuihe) of the Gongyu Expressway. In accordance with specified requirements, detailed records were made of the quantity, length, and location (latitude and longitude) of each type of pavement damage on the expressway. The elevation reference system used here is the 1985 National Height Datum, while the latitude and longitude coordinates adopt the CGCS2000 coordinate system. This dataset can provide a reliable basis for understanding the freeze-thaw distress conditions of the Gongyu Expressway and conducting relevant research.
