摘要 顶管技术已在地下管线施工中得到广泛应用,如何在施工中保障临近既有地下构筑物的安全问题日益突出。该文以杭州某穿越地下构筑物曲线顶管工程为背景,结合工程经验探讨总结出了减小周边环境变形关键施工技术措施,并提出了结合监测信息准确控制施工变形的施工方法,可为今后类似工程提供参考。 The pipe jacking has been wildly used in the construction of underground pipelines. How to ensure the safety of nearby existing underground structures and pipelines is the key issue in the construction. As an example of a curved pipe jacking crossing the underground structures and combined with the engineering experience, the article discusses and sums up the key construction technology measures to decrease the deformation due to the surrounding environment, and proposes the construction method accurately to control the construction deformation according to the monitoring information, which can be referred for the similar projects in the future.
