摘　　要：顶管作为城市管道的主要施工方式之一,应用广泛,在其施工过程中,如遇不良地质,土体加固方案正确与否往往关系着整个施工的质量及安全。结合工程实践,介绍顶管进出洞口时可能出现的风险并分析探讨针对此类问题有效的土体加固措施,给以后的设计及施工提供一些参考。As one of the main construction methods of urban pipeline, roof tube is widely used. In the process of construction, such as the bad geology, the correct construction of the soil is often related to the quality and safety of the whole construction. In this paper, combining with engi-neering practice, this paper introduces the possible risk of pipe jacking in and out of the mouth of the cave and analyze effective soil reinforcement measures for such problem, to provide some references for future design and construction.
