Combining with JiuhuashanTunnel Project

influence of blasting in tunnel excavation on ancient wall is calculated and analyzed. There is a section of acient wall on half way up Jiuhuashan Mountain

which the tunnel passes through. The wall has a history of more than six hundred years

and is necessary to protect carefully. Based on analyzing popular safety criteria

such as Blasting Safety Regulations

OSM blasting vibration safety criterion

Germany blasting vibration safety criterion

Switzerland blasting vibration safety criterion. The safety criteria of considering vibration velocity and vibration frequency have been adopted in many countries. The necessity of adopting the safety criteria of considering vibration velocity and vibration frequency is pointed out in the paper. Germany blasting vibration safety criterion is adopted to estimate the safety of the ancient city wall under the influence of blasting in tunnel excavation

applying several popular vibration velocity and vibration frequency formulas to calculate the extent and range of the influence of blasting in tunnel excavation on ancient city wall.
