Research on Techniques for Control of Tunnel Cutting Through Urban Road for Construction

When there is made the excavation of tunnel by drill-blasting method under shallow embedding and incompetent rock,safely and smoothly cutting through urban road needs to settle multiple technical issues and do well construction monitoring.In the light of practical project,the paper makes an approach to the theories about excavation construction and micro-vibration blasting,as well as the construction controlling techniques such as the leading tremie concrete supporting and the measurement monitoring etc,which possess an important instructing significance to simular project.
