【摘要】 通过对黄土场地爆破地震振动特征的观测分析,揭示了黄土地貌形态对爆破地震振动效应的放大作用,采用数值分析与现场试验对照研究的方法,探讨了爆破地震振动与天然地震振动之间的内在联系和本质规律。研究结果表明,采用爆破地震振动试验分析方法,可以较好地模拟黄土体的地震振动响应特点。更多还原

【Abstract】 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.更多还原
