발파진동현상 모사를 위한 수치해석기법 선정

초록

Linear and nonlinear models are available to simulate the effect of mine blasting. And the results are changed by selection of each model. Plaxis 8.0, FLAC 4.0 are used in this study for simulating blasting pressure. These programs offer linear model and nonlinear model. Linear model can properly simulate loss of impact wave in plastic failure region based on comparison of site vibration measurement and numerical analysis iteratively.
