摘要

爆破震动强度的预测一直是爆破震动危害控制的前提和基础，也是其研究的一个重要课题。基于有限元数值模拟方法的基础上对反映爆破震动强度的重要指标——质点振动速度的计算方法进行了探讨，并对空气和水两种不同间隔装药结构下的震动强度计算结果进行了对比分析。数值模拟结果表明，在爆心距不太大的情况下，计算结果与实测结果吻合较好，研究结果对爆破设计与施工有一定的指导意义。

Abstract

Forecasting of the blasting vibration is always the premise and basis of the controlling of the blasting vibration damage

and is an important subject of it. Based on the numerical simulation method of finite element

the calculation method of particle vibration velocity

an important index reflecting the blasting vibration intensity

is discussed; and an comparison analysis of the calculation results between two different kinds of charge structures decked with air and water is made. Numerical simulation results indicate that the calculation results are correspondent with the actual results if the distance from the blasting center is not far; it has certain significance to the design and construction of blasting.
