摘要
分析当前爆破地震效应及其影响因素的研究现状,通过分析土岩爆破的物理过程和爆破能量分配,探讨爆炸地震波的形成及传播特性。探索爆破震动在边坡中的传播衰减规律,研究爆破荷载作用下边坡的动态响应并寻求响应同爆源参数之间的对应关系,通过现场监测调整和优化爆破方案,提出切实可行的控制手段,为工程界解决相关问题提供理论参考。
The current blasting seismic effect and its impact factors of the status quo,through the analysis of soil physical process of rock blasting and the blasting of the distribution of energy to explore the explosion and the formation of seismic wave propagation characteristics,had been analyzed in this paper.Explore the blasting vibration in the slope of the spread of decay to study the blast loads and dynamic response of the slope to find the source in response to blasting parameters with the corresponding relation between,through on-site monitoring of the adjustment and optimization of blasting program,in order to put forward practical means of control is the urgent need for the engineering problems and provide a theoretical reference.
