摘　　要：针对长沙市岳麓区市政府站至雷锋大道站隧道爆破施工中引起临近企业商铺墙壁产生裂缝的现象,结合爆破装药参数与爆破振动监测数据,对该工程附近的企业商铺等建筑物进行安全评价。通过对构筑物墙体裂缝及爆破振动数据分析,得出隧道爆破施工中影响周围建筑安全的诸多因素,为优化爆破参数、降低爆破振动危害提供依据。The tunnel blasting vibration from Yuelu District City Hall Station to Leifeng Road Station in Changsha, Hunan Province caused lots of cracks in the wails of close enterprises and stores. In order to solve such problems, combined with the data obtained by monitoring of vibration and charge parameters, the safety of these buildings is evaluated. By analyzing the cracks in building materials and the blast vibration data, various factors affecting the safety of surrounding buildings during the blasting construction of the tunnels are obtained. Therefore, a basis for optimizing the blasting parameters and reducing damage posed by blast vibration can be provided.
