| Abstract: | Based on an engineering example,construction technical measures in a newly-built tunnel are introduced in this paper,including the adoption of short footages,weak blasting,strong supports,frequent measurements,and tight linings,which can reduce construction's influence on existing tunnels,and ensure the safe operation of existing lines,as well as the smooth construction of the new tunnel. |
