摘要
以别斯库都克露天煤矿为研究对象,通过室内岩石物理力学参数试验,建立了边坡振动的数值模型,得到了爆破振动作用下别斯库都克露天矿边坡岩体的动力响应特征,以及地震波在边坡岩体中的传播衰减规律,通过数值模拟结果与现场实测振动数据对比,验证了数值模拟分析边坡振动的可行性。
Taking Besikuduk Open-pit Coal Mine as the research object,we establish the numerical model of slope vibration through indoor rock physical and mechanical parameter tests and obtain the dynamic response characteristics of open-pit slope rock mass in Besikuduk Open-pit Coal Mine and the propagation and attenuation law of seismic waves in the slope rock mass under the action of blasting vibration.The article verifies feasibility of numerical simulation analysis of slope vibration by comparing the numerical simulation results with field measured vibration data.
