摘要
借助有限元数值分析软件Midas GTS NX,选取合适的岩土体本构关系、能够吸收动力波的粘性边界以及能够反映典型爆破的等效动力荷载,采用动力时程分析,计算隧道单段炸药爆破时对既有上部电力铁塔的影响。
With the help of the finite element numerical analysis software Midas GTS NX, this paper selected suitable rock-soil body constitutive relation, could absorb the viscous boundary of dynamic wave and could reflect the equivalent dynamic load of typical blasting, using the dynamic and time-historical analysis, calculated the influence to existing upper power iron tower in tunnel single-end explosive blasting.
