摘　　要：顶管施工作为一种常见的管道施工方法,因其非开挖或少开挖施工等优势,在城市基础设施建设中得到广泛应用。然而,顶管施工项目存在着一定的风险和挑战,施工过程中常常会引发地面沉降。本文针对海南省某一体化项目,通过对顶管施工项目风险的分析,应用peck法经验公式计算了路面沉降量。结果表明,顶管施工穿越段引发的路面沉降满足要求。研究结果可有效指导工程施工,并为顶管施工引起的地表沉降控制措施提供参考。Pipe jacking construction,as a common method for pipeline installation,has been widely used in urban infrastructure development due to its advantages of non-excavation or limited excavation.However,pipe jacking construction projects come with certain risks and challenges,often leading to ground settlement during the construction process.In this study,focusing on an integrated project in Hainan Province,the risks associated with pipe jacking construction were analyzed,and the settlement of the road surface was calculated using the empirical formula of Peck's method.The results indicate that the road surface settlement induced by the pipe jacking construction meets the requirements.The findings of this research can effectively guide engineering construction and provide references for controlling surface settlement caused by pipe jacking construction activities.
