摘　　要：文中以辽宁省输水二期项目柴河供水施工取水首部工程为依托,根据现场地质情况将该取水首部工程划分3个区域。设计中针对B区施工部位和围岩特征,采用松动爆破、明挖爆破以及预裂爆破等施工技术,为后期取水首部顺利实施起到重要的支撑作用。Based on the head water intake project of Chaihe water supply construction of the second phase of water transmission project in liaoning province,this paper divides the head water intake project into three areas according to the site geological conditions.In view of the construction site and surrounding rock characteristics in Zone B,construction technologies such as loose blasting,open cut blasting and pre-splitting blasting are adopted in the design,which play an important role in supporting the smooth implementation of the water intake head in the later stage.

关 键 词：取水首部 预留岩坎 松动爆破 明挖爆破
