Abstract: There are lithostratigraphic environments in the elevation range of shallow tunnel in urban. In such environment, ground surface is influenced by blasting vibration from borehole blasting method, which threatens the building on the ground. Based on JC3 segment of Jichang Road tunnel engineering in Xiamen, the propagation of vibration and its influence for ground surface were analyzed by in situ monitoring, then the blasting plan was optimized, in which the influence of vibration to ground surface was controlled.
