摘　　要：为控制既有隧道管片的变形,设计一种新型复合材料对地铁盾构隧道进行加固,并采用ANSYS对未加固及不同加固间距的隧道管片进行分析。研究结果表明,采用复合钢环加固后,隧道的收敛变形明显减小。隧道埋深越大,加固间距越小则加固效果越明显。In order to control the deformation of the existing tunnel segments,a new type of composite material was designed toreinforce the subway shield tunnels,ANSYS is used to analyze the unreinforced segment and the segnent with different reinforced spacing.The results show that the convergent deformation of the tunneis obviously reduced after the composite steel ring is adopted.The larger the tunnel depth and the smaller the reinforcementspacing are,the more obvious the reinforcement effect is.
