临近既有线路基边坡控制爆破技术

Controlled Blasting Technology of Subgrade Slope Adjacent to Existing Railway Lines

依托六沾复线W3标DK299+003.85～DK299+131.25段路基工程,探讨控制爆破施工的过程。阐述钻爆设计的方法、钻爆施工工艺流程和开挖步骤及方法,并给出技术保障措施,从中得出一些实践经验,为今后类似工程提供一些借鉴。

This article discusses the process of controlled blasting construction combining with Liuzhan multiple tracks subgrade slope engineering in the W3 bid DK299＋003.85～DK299＋131.25,expounds the design method and construction process of drilling and blasting technique as well as excavating steps and methods,and gives some technical security measures.We can draw some practical experiences which will provide some references to the similar project in the future.
