Analysis and Evaluation of the Ground Wave Propagation Due to Blasting Activities of the Road Construction by Numerical Models and Experiments

摘要

Blasting activities of the road construction could damage to the neigh-boring buildings because of the ground wave propagation. This paper focused on analyzing the numerical models of blasting in tunnel construction by using FEM software - MIDAS GTS NX and comparing to empirical measurements. From the results of analysis, we can identify the relationship of the wave propagation speed in the ground and the radius from the considering point to the source of vibration. Based on the results of this analysis assess the potential damage to neighboring buildings as well as designs the way to limit the impact of the wave propagation to neighboring buildings for similar projects.
