硐室加深孔预裂爆破能够显著地降低硐室爆破所带来的地震效应,有效地解决爆破振动所造成的边坡稳定性、边坡质量和爆区附近建(构)筑物的安全问题,适用范围比较大。太原—长治高速公路硐室加深孔预裂爆破的振动测试获得明显的降震效果,对同类工程具有参考价值。
The vibration testing analysis of blasting in Tai-Chang freeway show that it is chamber & deep-hole pre-splitting blasting that can strikingly drop the seismic effect of chamber blasting, so it effectively solves some problems of slope stability, slope quality and safety of building & structure that blasting vibration brings about. The improved technique of chamber blasting is beneficial to extending its scope of application so that it has reference value to similar engineering.
