| 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. |
