Research on Gradual Deformation and Fracture Mechanism of Landslide by Model Test

Abstract:

To study the gradual deformation and fracture mechanism of landslide, taking Han Jiaya landslide as the prototype, the laboratorial geo-mechanical model test with geometric similarity ratio 1:200 was carried out with several different materials to simulate corresponding rock layers and structure. By applying the digital close range photogrammetry, the deformation and fracture mechanism of the landslide under natural and excavating conditions are deeply analyzed. Comparing the results of model test with field monitoring analysis, the model test can quantitatively and qualitatively analyze the deformation and failure mechanism of the landslide by relatively accurate means. The landslide has been in good condition since this controlling engineering was completed several years ago. The study results provide an effective scientific basis for the prevention and treatment of the landslide.
