摘要(Abstract)：

济南旅游路的路堑爆破开挖工程属于复杂环境下的城镇石方控制爆破,在高频发射装置近区,采用爆破手段开挖石方路堑尚属首次。为有效地控制爆破震动,采用了孔内多段毫秒爆破技术,取得了理想的爆破效果。该技术为在复杂环境下实施深孔爆破提供了一种可行的途径,对同类工程具有一定的参考价值。
Cutting excavation of Jinan tour highway belonged to controlled blasting of mass rock in city in complex environment.It was the first case of adopting blasting method in cutting excavation near high frequency launcher.In order to control the blasting vibration effectively,down-hole millisecond blasting was employed and gave ideal effect.It provided a feasible approach to execution of deep-hole blasting in complex environment,having reference value to the similar engineering.
