Abstract

The rapid degradation of “Xing'an-Baikal permafrost” in Northeast China has led to various road engineering problems. Efficient inspection and control of pavement quality are critical for maintaining the structural integrity of roads and driving safety in cold regions. Taking the Jagdaqi-Walagan section (JWS) of the Jagdaqi-Mo'he Highway as the object, based on field investigation, unmanned aerial vehicle images and airborne LiDAR data, combined with geographical information system, this study analyzed the pavement damage characteristics in mid- to high-latitude permafrost regions, including quantification of damage ratio, extraction of pavement cracks, and evaluation of pavement roughness and driving quality. The results showed that the average pavement damage ratio was 8.80 %, significantly higher in isolated permafrost regions. A higher damage rate in the Jagdaqi-Mo'he direction than the opposite, with a more concentrated cracking distribution. The worst pavement roughness and most severe pavement bumping at repetitive repair locations. This study provides an effective method for investigating pavement damages and analyzing their mechanisms, and explores the application potential of visible light images combined with LiDAR data in frozen soil engineering. The results provide a scientific basis for assessing current highway conditions, enabling scientific maintenance, and evaluating the risk of engineering damages.

基于无人机图像和机载激光雷达数据的冻土地区路面损坏特征

中国东北地区 "兴安-贝加尔冻土 "的快速退化导致了各种道路工程问题。路面质量的有效检测和控制对于保持道路结构的完整性和寒冷地区的行车安全至关重要。本研究以加格达奇至莫贺公路加格达奇至瓦拉干段（JWS）为对象，基于野外调查、无人机影像和机载激光雷达数据，结合地理信息系统，分析了中高纬度冻土地区路面损坏特征，包括损坏率量化、路面裂缝提取、路面粗糙度和行车质量评价等。结果表明，路面平均损坏率为 8.80%，在孤立的永久冻土地区明显更高。贾克达齐-莫和方向的损坏率高于相反方向，裂缝分布更为集中。重复修补位置的路面粗糙度最差，路面磕碰最严重。这项研究为调查路面损坏情况和分析其机理提供了一种有效的方法，并探索了可见光图像与激光雷达数据相结合在冻土工程中的应用潜力。研究结果为评估公路现状、实现科学养护和评估工程损坏风险提供了科学依据。

期刊介绍： Cold Regions Science and Technology is an international journal dealing with the science and technical problems of cold environments in both the polar regions and more temperate locations. It includes fundamental aspects of cryospheric sciences which have applications for cold regions problems as well as engineering topics which relate to the cryosphere. Emphasis is given to applied science with broad coverage of the physical and mechanical aspects of ice (including glaciers and sea ice), snow and snow avalanches, ice-water systems, ice-bonded soils and permafrost. Relevant aspects of Earth science, materials science, offshore and river ice engineering are also of primary interest. These include icing of ships and structures as well as trafficability in cold environments. Technological advances for cold regions in research, development, and engineering practice are relevant to the journal. Theoretical papers must include a detailed discussion of the potential application of the theory to address cold regions problems. The journal serves a wide range of specialists, providing a medium for interdisciplinary communication and a convenient source of reference.
