隧道施工爆破震动对地面结构影响规律的研究

近年来城市隧道施工越来越多下穿居民区,开挖爆破对地表建(构)筑物的震动危害愈来愈受人们重视。该文以山东省青岛市区某公路隧道工程掘进开挖爆破的震动安全监测项目为依托,通过现场实测,对不同的隧道取得相应实测数据并进行回归分析,得到了地面建筑基础的震动速度衰减规律,为控制隧道矿山法开挖爆破对地面结构的危害提供基础数据。

Studies of Tunnel Blasting Vibration on Influence Rule of Ground Building

In recent years, more and more tunnels are increasingly constructed under urban residential areas; the harm effects of blasting vibration on the buildings attract more and more attentions. In this paper, based on a safety monitoring project of highway tunnels in Qingdao, and the field investigation, the regression analysis of the measured data is carried out, and the vibration velocity attenuation rule of the ground building foundation is obtained. It can offer some references for similar projects.
