摘要(Abstract)：

爆破荷载作用下岩体不可避免的会产生损伤,为了得到爆破荷载作用下岩体的损伤范围,根据应力波动作用和爆生气体的准静态作用,结合岩石破坏准则,对岩体在爆破荷载作用下的损伤范围进行了研究,得到了两者共同作用下岩体损伤范围的理论计算公式。结合福平铁路新鼓山隧道爆破掘进施工,对隧道周围岩体的爆破损伤范围进行了计算。结果表明,理论公式的计算值与现场实测值较为接近,验证了理论计算公式的合理性。对实际工程具有一定的指导意义。
In order to obtain the damage range of rock mass under the blasting load,according to the quasi-static action of the gas explosion and the blasting gas and the rock failure criterion,the damage range of the rock mass was studied and the theoretical calculation formula of rock mass damage range was obtained.Combined with the blasting excavation of the Xingushan tunnel in Fuping railway,the range of blasting damage of rock masses around the tunnel was calculated.The results showed that the calculated value of the theoretical formula was close to the field measured value,which verified the rationality of the theoretical formula.The practical project had a certain guiding significance.
