Multidimensional Quantification of Engineering Distresses and Secondary Periglacial Hazards Along Linear Infrastructure in the Permafrost Region of Northeast China Using UAV-LiDAR and Synchronous Visible-Light Imagery
Permafrost degradation is intensifying differential settlement, structural deformation, and secondary periglacial hazards along linear infrastructure in cold regions, underscoring the need for monitoring approaches that integrate corridor-scale screening with fine-scale quantification. This study investigated highways,...
