With the development of urban construction, the advantages of trenchless technology such as less negative effects and occupied field as well as lower influence on road traffic and normal life develop rapidly. Taking jacking method as and example, this paper introduces the working mechanism of trenchless technology and its application in municipal pipeline project. Based on that, this paper puts forward the difficulties it faces such as imperfect technical standard, poor observability and existent risks. At last, this paper proposes the prospect of trenchless technology.%随着城市建设的不断发展,非开挖技术以其施工负面影响较小、所占场地较少、对道路交通及人们正常生活影响较微弱等优势得以迅速发展.以顶管法为例,介绍非开挖技术工作机理及其在市政管网工程中的应用,并在此基础上提出了非开挖技术所面临的困难,如非开挖技术标准和规范尚不完善,直接可观察性较差,以及存在建设风险隐患等,最后对其发展前景进行了展望.
