青藏工程走廊多年冻土区地表InSAR形变监测数据集（2017–2022年）

在全球变暖和人类活动的双重作用下，位于青藏高原腹地的青藏工程走廊多年冻土区段多年冻土退化强烈，从而引发了一系列病害问题，这为位于其内的青藏公路、青藏铁路等线性工程基础设施的维护和安全带来了较大的困扰。地表形变作为路基病害及环境地质灾害的第一表征，可以对工程病害进行有效的指示，但到目前...Driven by the combined effects of global warming and human activities, the permafrost sections along the Qinghai-Tibet Engineering Corridor in the hinterland of the Qinghai-Tibet Plateau have undergone intense permafrost degradation, triggering a series of engineering and environmental geological hazard issues. This has posed significant challenges to the maintenance and safety of linear engineering infrastructures such as the Qinghai-Tibet Highway and Qinghai-Tibet Railway located within this corridor. Surface deformation, as the primary manifestation of subgrade distresses and environmental geological disasters, can effectively indicate the occurrence of engineering distresses; however, so far...
