摘要
以福州南站风井的开挖施工为工程依托,针对常规爆破对环境扰动大等工程特点,对静力爆破开挖施工方法进行研究。在福州南站小里程风井的施工过程中使用静力爆破技术对岩体进行破除,解决了在特殊环境中不适宜使用常规爆破方法对岩体进行开挖施工的工程问题。从施工过程来看,该施工方法引起的变形小,对周边环境没有造成干扰和破坏,既保证了工程安全的要求,同时也在一定程度上缩短了工期。
Based on the construction of ventilation shaft of Fuzhou south railway station,the static blasting construction method is studied according to the characteristics of large environmental disturbance caused by conventional blasting.In the construction process of the small mileage air shaft of Fuzhou south railway station,static blasting technology is used to break the rock mass.From the perspective of the construction process,this construction method causes minor deformation,which not only ensures the safety requirements of the project,but also reduces the construction period to a certain extent.
