Representative Achievements

Being full of understanding slope of dynamic response that is necessary to analyze slope instability mechanism under action of earthquake. It is also the basic to evaluate slope dynamic stability. On the basis of homogeneous slope dynamic response, the investigation on the impact mechanism and characteristics of slope dynamic response due to geological structure is proposed in the project. Guantan landslide is choosed as the prototypes in the project, which is generalized as conception model on the base of field investigation, experimental tests and mechanism analysis. Using the variables of geometric parameter and physical mechanics parameter, the series of rock slope model with double layer rock stratum and dipping inside structure will be constructed. The dynamic response mechanism of the slope of the assigned geological structure is systematically investigated by the integrated way of seismic model experiment and numerical simulation computer, which can offer the scientific basis for earthquake geology disaster assessment. In this study, the seismic response characteristics of rock slope was studied by the physical model test, numerical simulation way. the influence of incident wave amplitude, frequency, slope angle, slope angle and slope height on the dynamic response of slope was analyzed. The seismic dynamic response characteristics of the inner slope with the spallation and inversion are fully realized. From the point of view of quantification, the simple formula of the vertical depth range of the anti- inclined slope under seismic action is obtained. The landslide mechanism of Guantan was studied under earthquake. The simulated data show the tensile deformation process of the upper and lower extrusion during the process of the landslide development. The slope structure and rock mass structure are important factors in determining the landslide development. So on the basis of the original research plan, this research has carried on the work of the discontinuities Characterization and the intersection calculation of the fracture.
