Abstract

Landslide hazard is often seen in the boundary of loess platforms in northwest China. There are more than 60 loess landslides recorded in Jingyang platform in the past five decades. Two types of the loess landslide, which are flowslide and slide, have been categorized. In this study, a statistical analysis to characterize the loess landslides was conducted. Additionally, a series of constant shear drained (CSD) triaxial tests were undertaken to reveal the triggering mechanism of the loess landslides. The irrigation-water infiltration and sequence and rule of loess landslide play a crucial role in triggering the loess landslides. These results provide the insights into the countermeasures recommended to resist the loess landslide hazard, thereby reduce the potential of loess landslide in the future.
