Study on the Vibration Variation of Rock Slope Based on Numerical Simulation and Fitting Analysis

In engineering blasting, the slope surfaces in blasting area exert various effects on blast vibration velocity. For example, effect and whipping are generated area, which will influence The is key protection for many projects; therefore, it of practical value to explore surface speed prediction against it. velocity was analyzed by numerical simulation fitting. field monitoring data were fitted formula. According obtained fitting formula, we inferred that amplification occurred area. Numerical carried out using ANSYS/LS-DYNA program. Using above two methods, whether whip tip study verified. By simulation, established three-dimensional (3D) models four different working conditions. We simulated complete process consistency between results, proved reliability simulation. Based results explored variation under height difference Finally, distribution law at inside slope.
