摘　　要：结合上海污水治理工程大口径长距离曲线顶管的施工,介绍了采用长距离曲线顶管的原因及其施工存在的风险。通过施工实例,分析了施工过程中发生轴线严重偏差的原因,叙述了纠偏的具体措施和纠偏过程。实践验证措施有效,有一定的参考价值。Combined with large diameter long-distance curved pipe-jacking construction of Shanghai sewage treatement projects, the reasons and the risk of long-distance curved pipe-jacking have been introduced in this paper. Through a case, the reasons of serious axis deviation are analyzed; the detailed measures and the process of correcting errors are presented. Finnally, the testing measures are proved to be effective and full of reference va- lues.
