摘　　要：针对34‰大纵坡、300m小半径曲线盾构接收施工技术要点。本文以杭州地铁7号线工程九工区盾构项目为例,着重从重难点把握、施工技术措施等方面,探索大坡度、小半径接收盾构施工技术,以达到为后续施工起借鉴作用的目的。The key points of receiving construction technology for 34‰large longitudinal slope and 300m small radius curve shield machine.Taking the shield project of No.9 work area of Hangzhou Metro Line 7 project as an example,this paper explores the construction technology of large slope and small radius receiving shield from the aspects of key and difficult points and construction technical measures,so as to achieve the purpose of reference for subsequent construction.

关 键 词：大坡度、小半径盾构接收 施工技术
