Modeling Test on Typical Deformation Fracture Mechanism of Slope in High Earthquake Intensity Areas
The deformation fracture of slope caused by earthquake is a complicated process. In this paper, three typical geomechanical modes are summarized and concluded, i.e. the outerinclining bedded landslide model, the high-steep block (layer) bedded slope collapse model and the weak base landslide model, which are representative for the deformation fracture and instability of slope in areas with high earthquake intensity. We have also designed a set of geomechanical modeling test equipment, and developed corresponding models and techniques under vibration so as to conduct the mechanism test of the three typical geomechanical models. Through the modeling reproduction test of the process of deformation fracture, its typical characteristics under vibration are shown. Formation conditions, relevant factors and evolvement principles of typical instability mechanism due to earthquake are presented to offer scientific and reliable test data and a basis for further research and analysis.
