硐室加深孔预裂爆破的振动特征

Vibration Characteristics of Chamber and Deep-hole Pre-splitting Blasting

太长高速公路的爆破振动测试分析表明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。这种改进的硐室爆破技术有利于扩大其适用范围,对同类工程具有一定的参考价值。

The vibration testing analysis of blasting in Tai Chang Exprassway shows that chamber ＆ deep-hole pre-splitting blasting can strikingly drop the seismic effect of chamber blasting, so it effectively solves some problems of slop stability, slop quality and safety of building structures caused by blasting vibration. The improved technique of chamber blasting is beneficial to extending its scope of application.
