| Abstract: | Only by adopting vibration reducing controlled blasting technology, can the buildings with poor vibration resistance in busy urban area avoid to be damaged by blasting vibration from excavation of shallow tunnels underground. In the light of an engineering example, some key technologies such as mini bench constructing method, vibration reducing cutting and linear blast hole layout were expounded in this paper. |
