The cyclic expansion and contraction characteristics of a loess slope and implications for slope stability [PDF]
Scientific Reports, 2021 Loess covers approximately 6.6% of China and forms thick extensive deposits in the northern and northwestern parts of the country. Natural erosional processes and human modification of thick loess deposits have produced abundant, potentially unstable ...

Analysis of the effects of vertical joints on the stability of loess slope [PDF]
Scientific Reports, 2023 Vertical joints with different lengths and slope distances (the horizontal distance from joints to slope shoulder) are generated at the top of the loess slope because of the unloading and collapsibility of the loess. The existence of vertical joints is a

Model Test on Acoustic Emission Monitoring of Loess Slope Failure. [PDF]
Sensors (Basel)The three stages of loess collapse are characterized by notable concealment and sudden onset due to the sudden nature of loess collapse and the prolonged duration of the peristaltic deformation stage. Traditional displacement monitoring methods struggle to detect early signals of instability and failure, leading to poor timeliness in disaster warnings.
