Journal Article
Slope engineering in the deeply incised valleys of the Tibetan Plateau: key challenges and strategic considerations
Objective As human engineering activities expanded into the Tibetan Plateau and its surrounding areas, slope instabilities—particularly large-scale landslides—in deeply incised valleys have occurred with increasing frequency, posing severe threats to major infrastructure projects and public safety…

Numerical simulation analysis of seismically triggered load and ball-and-pillow structures in the lacustrine sediment
Objective Seismically triggered soft-sediment deformation structures (SSDSs) in the lacustrine sediments serve as reliable stratigraphic records for studying paleoearthquake events in tectonically active regions. Load and ball-and-pillow structures, as common types of SSDSs, are generally…

Formation and modification of the Minle Basin in the Hexi Corridor: Insights into Cretaceous tectonic characteristics of the northeastern Tibetan Plateau
Objective A series of Early Cretaceous sedimentary basins developed in the Hexi Corridor along the northeastern margin of the Tibetan Plateau. These basins preserve critical records of the regional pre-Cenozoic tectonic evolution, forming the basis for understanding the Cenozoic growth mechanism of…

Study on the source characteristics and seismogenic structure of the 2021 Yangbi MS 6.4 earthquake sequence
Objective On 21 May 2021, an MS 6.4 earthquake struck Yangbi County, Dali Prefecture, Yunnan Province — the largest event near the Weishan Basin segment of the Weixi–Qiaohou fault since 1976. The mainshock produced no surface rupture and did not occur on any known active fault. Despite numerous…
