EFFECT OF BLAST-INDUCED GROUND MOTION IN LOESS SITES
黄土场地的爆破地震振动效应

Geomorphologic characteristics in loess areas are closely related to earthquake disasters. Based on the analysis of characteristics of blast-induced ground motion in loess sites,the amplification effect of blast-induced ground motion in different geomorphologic units is revealed. Through comparison of numeric analysis and in-situ test,the inherent relation between blast-induced ground motion and earthquake ground motion is studied. The research shows that blasting test method is feasible in simulating the earthquake response characteristics of loess.
