Abstract
The characteristics of the loessial landslides induced by the Minxian–Zhangxian 6.6 earthquake, Gansu province, China in 2013 were studied based on field investigation, laboratory tests and analysis. The influence of heavy rainfall before the earthquake on seismic safety of loessial slopes was analyzed. The mechanism of a large scale of loessial landslide in Yongguang village triggered by liquefaction during the shaking, which killed 12 people, was revealed. Moreover, the method of evaluating the maximum sliding distance of loessial slopes under the effect of earthquakes was provided based on the data on 86 loessial landslides induced by earthquakes. Furthermore, the strategy of preventing and mitigating disasters caused by seismic loessial landslides was proposed.
