摘要
基于行车振动与爆破振动输入建(构)筑物能量的等效性,推导了行车振速换算成等效爆破振速的公式。探讨了参考爆破安全标准评价行车振动安全问题的方法。根据实测公路来往行车质点振动速度资料,将其换算成等效爆破振速,结果表明:多数工况下行车振动输入建筑物的最大输入能量密度与常规隧洞钻孔爆破相当;部分行进中的重型车辆与钻爆开挖对某些建(构)筑物结构造成的振动影响在同一量级。
Based on the equivalent energy content inputted to structures and buildings by traffic vibration and blasting vibration,a conversion formula about traffic vibration velocity and equivalent blasting vibration velocity was derived. A method of assessment of the traffic vibration safety problems was discussed with reference to the blasting safety standard. According to monitored traffic vibration velocity data, the equivalent blasting vibration velocity was converted. The results shows that the maximum input energy densities of traffic vibrations in most conditions are tantamount to normal tunnel blasting excavations. The impact of vibrations on some structures and buildfngs induced by some heavy vehicles axe in the same magnitude as which induced by drilling and blasting.
