%X In general,as the distance between double line tunnel and existing tunnel is very small,excavating blast in double line tunnel will affect structure safety of existing tunnel. The effect factor of excavating blast in double line tunnel on existing tunnel is first analyzed. In addition,the finite element method is applied to analyze the effect of blast vibration,and excavating blast in Guanzhai double line tunnel is taken as an example. The results show that finite element method can fully describe the whole process of blast vibration.
