But due to subway construction relates to underground geological strata, geologic layer and complex situation; it has great influence on the subway construction. Especially in the construction process of the selection of blasting scheme, construction safety, construction quality control and vibration control are the subway construction the difficulty, therefore, this paper in view of the Qingdao Dunhua Road subway pylon type metro station, hope that through reasonable design of blasting scheme, reduce over break and under break, controlled blasting on the surrounding rock disturbance, in order to achieve security complete station construction, ensure the quality of construction. In this project is mainly to solve the problem of Qingdao Dunhua Road subway station the main line of the tunnel and admit blasting design, the first tower type metro station design method, chamber is more, construction is complex, on the surrounding rock pillar protection, tunnel cross section form, tunnel lining structure, construction method, initial supporting structure model, parameter and so on are new and higher requirements. Therefore in the blasting design process, we used a bench excavation, large diameter hollow hole, excavation, piecewise detonating method, at the same time, a detonation subsection delay blasting excavation patent technology, at the same time, a detonation subsection delay blasting excavation patent technology, the spirit of multiple drilling, charging less, short footage principle, strictly control the footage, single hole charge, in the design of the A cross passage, was a
