【摘要】 以厦门环岛干道白城隧道为例,介绍复杂环境条件下浅埋软岩隧道减震爆破施工方法。爆破开挖中,通过在掏槽眼部位布置空孔、在周边眼部位布置减震孔的措施,并通过采用不偶合间隔装药、毫秒延时爆破、实时地震波监测等措施,实现了隧道周边围岩的稳定和隧道地表不同结构房屋的安全。更多还原

【Abstract】 Based on Xiamen island ring road tunnel of Bai Cheng,the article introduces the blasting construction method under the complex environmental condition of the shallow buried soft rock tunnel.In blasting excavation,through measures of layout empty eyes in the cuthole,decouple eyes in circum,and so on,and by the use of the not coupling interval explosive charges,delay millisecond blasting,Real-time monitoring seismic waves and other measures,the stability of surrounding rock and the security of the different structure houses on the surface of tunnel are ensured.更多还原
