中尼交通廊道（国内段）冻融灾害及冻土工程病害调查数据（2023）

该数据集为中尼交通廊道G318（日喀则-拉孜县-聂拉木县-樟木镇）、G219（聂拉木县-吉隆县）、G216（吉隆县-吉隆口岸）、Z715/S303/G563（定日县-定结县-萨迦县-日喀则市）沿线路基/路面工程、桥梁工程、水利工程、交通附属设施病害及冻融灾害调查数据集。调查病害类型主要包括不同类型冻融灾害及路基/路面工程、桥梁工程、水利工程、交通附属设施病害。采用人工调查的方法，观察各类病害破损情况，按要求详细记录灾害/工程病害数量（范围）、破坏特征及所在位置。该数据集可为全面了解中尼交通廊道（国内段）主要公路工程及拟建铁路沿线冻融病害情况及相关研究提供依据。平面坐标系：WGS1984。

This dataset is a field survey dataset focusing on defects and freeze-thaw disasters of subgrade/pavement works, bridge engineering, water conservancy facilities and traffic ancillary infrastructure along the China-Nepal Transportation Corridor routes including G318 (Xigazê – Lhazê County – Nyalam County – Zhangmu Town), G219 (Nyalam County – Gyirong County), G216 (Gyirong County – Gyirong Port), and Z715/S303/G563 (Tingri County – Dinggyê County – Sakya County – Xigazê City). The surveyed defect categories primarily cover various freeze-thaw disasters as well as defects in subgrade/pavement works, bridge engineering, water conservancy facilities and traffic ancillary infrastructure. Manual field surveys were conducted to observe the damage status of all types of defects, with the quantity (scope), damage characteristics and location of each disaster/engineering defect recorded in detail per specified requirements. This dataset can serve as a critical reference for comprehensively understanding the freeze-thaw defect conditions along the major highway projects and proposed railway lines within the domestic section of the China-Nepal Transportation Corridor, and support relevant academic and engineering researches. Planar coordinate system: WGS 1984.
