谈高速铁路隧道施工控制爆破方案设计

Discussion on the blasting scheme design of high-speed railway tunnel construction control

就京沪高铁金牛山隧道下穿既有公路的综合施工技术作为研究内容,结合金牛山隧道的特点,采用经验公式对爆破方案进行设计,以此确定单段最大装药量,从而为工程实践提供参考。

Taking the comprehensive construction technology of underneath pass existing highway of Beijing-Shanghai high-speed rail Jinniu Mountain as the research content,combining with the characteristics of Jinniu Mountain tunnel,using empirical formula designed the blasting scheme,in order to determine the single maximum charge,so as to provide reference for engineering practice.
