摘要：  
以重庆轨道交通环线二期凤凰站～奥陈区间明挖段为例，对城市轨道交通大断面暗挖车站水压爆破施工优化总结。考虑爆破震动、污染对临近建筑物、居民的影响及车站顶部埋深浅、大断面暗挖、地表动荷载大等因素进行水压爆破优化设计、加强爆破监测等，通过实践证明，施工方法可行。
Abstract：?  
Taking the open-cut interval section in the second phase from Fenghuang Station to Aochen Station of Chongqing Rail Transit Circle Line as an example,this paper summarizes the optimization of construction technology of large-section under-excavated station with water pressure blasting method for urban rail transit.Considering many factors such as the blasting vibration,influence of pollution on the nearby buildings and the residents,the shallow-buried depth at the top of the station,large-section excavation and large dynamic loading,the optimization for water pressure blasting is seriously de-signed and blasting monitoring is strengthened.Practice has proved that the construction method is feasible.
