Key points
- Numerical simulations of rock slope blasting behavior align with field test results for particle vibration velocity.
- An elevation amplification effect is observed in particle peak velocity during attenuation.
- Surface particles of the slope experience higher vibration velocity and maximum displacement compared to internal particles.
- The pattern of maximum particle displacement under blasting is not clearly defined.

Abstract
Based on the blasting vibration field test of a high cutting rock slope of Guanghe expressway in Guangdong province, numerical simulation is employed to estimate the dynamic behavior of the slope under blasting load. A simplified triangular blasting load is adopted to simulate the explosion. The velocity and displacement fields of the slope under blasting are analyzed and the result shows that the particle vibration velocity by the numerical simulation is basically consistent with that by field test. Elevation amplification effect exits in the process of attenuation of the particle peak velocity. The result also indicates that the particles on the surface of the slope have larger velocity and maximum displacement than the particles inside the slope, and the maximum displacement of particles does not have obvious rule to comply with.
