封面故事:新疆伊宁县皮里青河“3.24”滑坡无人机影像。近几十年来, 全球气候变暖导致常年冻土区和季节冻土区崩塌、滑坡、泥石流等地质灾害频发。伊犁河谷地处我国天山山脉西段, 属于典型的季节性冻土区。其冻融型黄土滑坡具有浅表层、多期次及渐进式滑动的特点。通过研究黄土滑坡冻融失稳机理与滑坡运动特征, 表明地下水水位上升导致孔隙水压力增大是滑坡冻融失稳的主要原因。该项研究成果为同类型滑坡的早期识别与风险评估提供了范例和技术支撑。详见本期339-349页。(图片提供:朱赛楠)

Cover Story:UAV (Unmanned Aerial Vehicle) image of “3.24” landslide that happened along Piliqing River in Yin-ing County, Xinjiang. In recent decades, the global warming has led to the frequent occurrence of such geohazards as rock collapse, landslide and debris flow in the permafrost areas and seasonal frozen ground areas. The Yili River valley lies in the western segment of the Tianshan Mountains and belongs to a typical seasonal frozen ground area. The freeze-thaw loess landslide is characterized by shallow, multi-phase and progressive sliding. Based on detailed field investigation, dynamic comparison of multi-phase remote-sensing images and numerical simulation, the authors studied the freeze-thaw instability mechanism and movement characteristics of the loess landslide. And the results show that the increase of pore water pressure resulting from the uprising of the groundwater level is the major reason responsible for the landslide freeze-thaw instability. This research achievement has provided a good example and technical support for the early identification and risk assessment of the same type landslide. For details, see pp. 339-349 of this issue.
