摘　　要：通过采取增设中继井、加强地面观测和套管修复等措施,同时利用原有接收井作为工作井尝试反向顶进与之交汇,成功地解决了顶管施工中因遇到孤石、砂砾石等复杂地质情况,而造成机头无法顺利顶进及混凝土套管破裂等问题,为类似工程的施工提供了新思路。In this paper,by adopting measures such as adding relay Wells,strengthening surface observation and casing repair,and using the original receiving well as the working well to try to cross with it in reverse jacking,this paper successfully solved the problems such as the head can not be jacking smoothly and the concrete casing is broken due to complex geological conditions such as isolated stone and gravel in pipe jacking construction,and provided a new idea for the construction of similar projects.
