Landslide disaster in the loess area of China
Journal of Forestry Research, 2002China is the country with most widely distributed loess area in the world, and its loess area accounts of 6.63% of total nation land area. The landslide disaster occurs frequently for complex natural condition and becomes major factors hindering the social and economic development of loess regions.

The Physical and Mechanic Properties of the Loess Landslide
Advanced Materials Research, 2012The loess landslide in BaDong city, HuBei province China suffers great losses, which is an extremely typical landslide disaster. Variation in water level in the Yangtse River and rainfall has enormous influence on the loess landslide disaster. Some tests on loess have been done, which mainly include water content influence on shear strength of the ...

A loess landslide induced by excavation and rainfall
Landslides, 2013The initiation of loess landslides is a common engineering problem during the construction of the expressway or other engineering works in the Loess Plateau of China. The engineers and researchers should devote themselves to the prevention of the initiation of loess landslides.

Localised Fluidisation in a Giant Loess Landslide
Engineering GeologyOn 1 September 2022, a giant loess landslide occurred in Huzhu Tu Autonomous County, Qinghai Province, China. This catastrophic event brought to light a unique fluidisation phenomenon, which was confined to specific areas of the landslide. In certain parts of the landslide, the loess fully transformed into a viscous, fluid-like state, while other parts

Modelling landslide distribution on loess soils in China: an investigation
International journal of geographical information systems, 1992Abstract Catastrophic landslides are a severe environmental problem on the Loess Plateau of China. In order to establish which slopes are most at risk, their spatial incidence can be modelled using geographical information systems techniques together with a database describing the past landslides.

A recurrent composite loess landslide in southwestern China
Quarterly Journal of Engineering Geology and Hydrogeology, 2018A loess landslide occurred in southwestern China on 21 September 2016. The field investigation performed 2 months after this event revealed that this slope failure was a partial reactivation of a landslide initiated in 1995, with a first-time failure in 1975. This landslide has been triggered three times, each having a distinct mode.

Controlling factors of loess landslides in western China
Environmental Earth Sciences, 2009Based on detailed field data from recent geo-hazards surveys in the Loess Plateau region of western China, this study analyzes the key factors that control loess landslides. The evolution phase of river valleys, the geological structure of slopes and the geometry of slopes are all found to play a role in determining the occurrence, distribution and ...

Types and characteristics of loess landslides at Heifangtai Loess Plateau, China
201020世紀60年代末期,為了安置劉家峽、鹽鍋峽庫區移民,在黑方臺建成了提水灌溉工程,造成地下水位上升,誘發了大量黃土滑坡。作者于2006-04～2007-09先后對黑方臺黃土滑坡進行了野外調查。利用IKONOS影像對黃土滑坡進行了遙感解譯,將其與研究區數字高程模型(DEM)進行疊加再現了滑坡場景。基于以上工作,首先對黑方臺黃土滑坡進行了較為系統的分類,包括黃土泥流、黃土滑動、黃土-泥巖接觸面滑坡、黃土-泥巖順層滑坡和黃土-泥巖切層滑坡。黃土泥流集中發育于野狐狗北部凹地形處;黃土-泥巖滑坡受基巖傾向控制,分布于坡向150°～200°的塬邊地段。農業灌溉補給地下水的增濕、軟化作用是黑方臺黃土滑坡的根本誘發原因。對黑方臺黃土滑坡機制的研究進行了展望。

The Mechanisms for Initiation and Motion of Chinese Loess Landslides
2012Loess is a wind-blown sediment with characteristic loose structure and low water content. Moisture content and confining stress are the key factors controlling the mode of its deformation and failure. CU tri-axial tests suggest that in low moisture content and low confining stress, loess fails by cracking with the development of vertical fissures while
