According to the example of Wenchuan earthquake, a fast estimation method of damage range is proposed and discussed. 结合汶川地震的震例,本文总结给出了一个快速估计破坏范围的综合方法。
The accumulative damage range of surrounding rock is mainly determined by the blasting of excavating face of pilot tunnel I which is parallel to it. 侧壁围岩的累计损伤范围(DR)主要由与其齐平的导洞I的开挖掌子面爆破决定;
Numerical simulation and experimental study of damage range of surrounding rock in large tunnel under blasting excavation 大断面隧道爆破开挖围岩损伤范围(DR)试验研究及数值计算
The results of comprehensive damage consequences model of FAE showed that the fragment had the greatest damage range, followed by shock wave and thermal radiation, while suffocation effect took nearly no action to people in the open explosion space. FAE综合毁伤后果模型的结果表明,破片是燃料空气炸药作用范围最大的毁伤方式,其次是冲击波、热辐射,而窒息效应在野外空旷爆炸场对人员几乎无作用。
According to earthquake parameters and geologic structure ec. damage range, building destruction, economic loss and personnel casualties can be rapidly estimated. 依据地震发生的基本参数、地震地质条件等预估灾害范围、建筑物破坏程度、经济损失、人员伤亡等情况,给出地震发生早期影响尺度的快速预测结果。
