The invention relates to the technical field of
geological disaster prevention and control, in particular to a
rock engineering slope stability classification method. According to the technical scheme, the method comprises the following steps: obtaining
spatial distribution characteristics of a slope
structural plane through combined detection of three-dimensional
laser scanning and a geological
radar, and establishing a quantitative
index system containing occurrence, density and
connectivity of the
structural plane; the method comprises the following steps: acquiring a fracture
signal in a slope in real time by adopting a micro-seismic
monitoring system, and extracting a micro-seismic event energy release rate, a
dominant frequency offset and a seismic source mechanism parameter through time-
frequency analysis; and constructing a geologic structure evolution inversion model, reconstructing a geologic structure evolution process based on the regional geologic
database and the field drilling data, and calculating the distribution characteristics of the
residual stress field of the structure. According to the method, comprehensive, accurate and real-time monitoring and classified evaluation of the
rock engineering slope stability are realized, potential risks can be effectively predicted, a scientific and accurate decision basis is provided for slope support and treatment, and the safety and stability of the
rock engineering slope are greatly guaranteed.
