Based　on　the　blasting　excavation　of　the　Xisiduhe　tunnel　of　the　Huaichang　Road　reconstruction　project,　the　technology　for　monitoring　and　controlling　blasting-induced　vibration　during　tunnel　construction　is　addressed　in　this　paper.　By　monitoring　the　particle　vibration　velocities　on　the　ground　surface　and　in　the　structure,　the　transmission　law　of　the　blasting　vibration　wave　is　studied　and　a　spectral　analysis　is　conducted.　Finally,　a　rational　controlling　technology　is　presented.　The　results　of　monitoring　analysis　show　that:　(1)　the　magnitude　of　the　particle　blasting　vibration　velocity　is　closely　related　to　the　maximum　explosive　charge　of　each　blasting　and　the　distance　between　the　monitoring　points　and　the　blasting　center;　(2)　for　left-　and　right-part　blasting　excavations　on　the　lower　bench,　the　larger　the　clamping　force　of　the　first　blasting　on　the　rocks,　the　bigger　the　blasting　vibration　response　and　the　higher　the　vibration　velocity.　Because　the　first　blasting　offers　a　new　free　face　to　the　second　blasting,　it　can　mitigate　the　blasting　vibration　effects　and　decrease　the　vibration　velocity;　(3)　since　the　high-frequency　components　of　the　particle　vibration　velocity　are　not　abundant,　the　dominant　frequency　of　the　vibration　velocity　is　mainly　distributed　in　low-frequency　band;　(4)　because　the　air　vents　laid　on　the　covered　arch　at　the　cut-and-cov-er　section　generate　the　reflecting　action　of　a　stress　wave,　the　blasting　vibration　has　a　significant　influence　on　the　reinforced　concrete　covered-arch　structure.
