located on the section of k15+000-k15+500 of the Lanzhou-Lintao expressway
is a bedding landslide triggered by cutting the high and steep slope. The landslide has been slided during excavation and exertion of the highway. It is a large-scale and harmful landslide with the characteristics of repetition and succession due to its geological condition
rock mass structure and the design of the slope of the expressway. Based on geological condition
project feature and the characteristics and history of sliding
the causes of occurrence and the mechanism and process of evolution of the landslide are comprehensively analysed by using engineering geology
physical model test and FLAC3D numerical simulation.
