摘　　要：青草沙凌桥支线C3标第一次将复合管材应用于长距离压力曲线管道施工。在曲线顶管施工过程中,管口在节间转动过程中受力状态复杂,容易破坏,为传力的薄弱环节。该文就复合管材在长距离压力曲线顶进过程中如何进行管口的保护做了研究,建立了有限元模型,从力学角度分析了管口受力情况,针对其受力特点制定了相应的保护措施,保证了顶管完成后压力试验的顺利进行及通水后的正常运营。研究可为复合管材应用于压力管道施工提供有益的借鉴。Composite pipe was first used in the long-distance curve pressure tunnel of Qingcaosha Lingqiao C3 extension line. During the period of jacking, joint of curve pipe is a weak point, the stress state is complex and can be destroyed easily when rotating. Based on this project, protection of pipe joint was studied, FEM was established, the stress condition of pipe joint was analyzed and protection methods was summarized to ensure the pressure experiment can be carried out after pipe jacking and the tunnel be used safety after piping water. The research is a useful reference for similar projects.
