摘　　要：为了研究软土地区顶管下穿施工过程主要控制因素对路面沉降变形影响规律,以广东省某软土地区顶管项目为背景,采用Peck公式法对地面沉降进行了理论计算,通过大型有限元软件Plaxis3D对顶管过程进行了数值模拟计算。模拟计算结果与理论计算、监测数据基本吻合,最终得出顶管埋深(H)和顶管管径(D)对路面沉降的影响规律。In order to study the influence of the main control factors on the settlement and deformation of the pavement in the construction process of pipe jacking in soft soil area,this paper uses the Peck formula method to calculate the ground settlement based on the pipe jacking project in a soft soil area of Guangdong Province and uses the finite element analysis software Plaxis3D to simulate the pipe jacking process.The simulation results are basi⁃cally consistent with the theoretical calculation and monitoring data and finally the paper obtaines the influ⁃ence rule of pipe jacking depth(H)and pipe jacking diameter(D)on pavement settlement.
