【摘要】 考虑爆破地震波在传播过程中的时程效应和条块间的法向力,结合关于动力放大系数的最新研究成果,采用拟静力化的惯性力法,提出新的岩质高边坡在爆破时的动力安全系数计算方法。通过案例证明,该方法能够综合考虑地震波在岩石介质中传播的衰减和频谱结构特性及相位差等因素,因此较毕肖普拟静力法更具理论基础,其结果更加贴近工程实际。更多还原

【Abstract】 Considering the time-distance effect and normal force between slices in the transmission process of blasting seismic wave,and combining the latest researches about dynamic magnification coefficient,a new dynamic safety coefficient calculation method for the high rock slope blasting was put forward by using quasi-static method.The cases proved that the method can comprehensively consider attenuation,spectrum structure characteristics,phase difference and other factors of seismic wave propagation in the rock medium.Therefore,the method had a better theoretical basis than the Bishop quasi-static method,having a more precise results with engineering practice.更多还原
