摘要
结合沪昆客专贵州段茅坪山隧道掘进工程,论述了隧道掘进水压爆破技术的具体含义,及其与常规爆破掘进技术的炮孔装药结构与爆破参数对比结果,通过技术与经济指标分析计算,突显了隧道掘进水压爆破技术"三提高一保护"的作用与效果;并就如何进一步推广隧道掘进水压爆破技术总结出4点认识与体会,可供类似工程参考与借鉴。
Combined with Maopingshan tunnel driving engineering of Guizhou section in Shanghai-kun- ruing passenger dedicated line, the specific meaning of hydraulic blasting technology in tunnel driving was discussed, and the comparison results of charge structure and blasting parameters were given between it and conventional blasting driving technology. The effect of three improvements and one protection was highlighted, by analysis calculation of technical and economic indexes. The four points of knowledge and views were summarized about bow to further extend hydraulic blasting technology in tunnel driving. It could be referred for similar engineering.
