摘　　要：顶管施工是非开挖施工中的重要手段,它可以从土层内部穿越,对沿线公路及建筑等不产生破坏。结合工程实际,通过应用触变泥浆技术、应力释放孔技术等技术手段解决了大直径排水管顶管施工过程中容易出现的管身偏位、周边建筑物或管线变形过大等不利因素,以期为类似工程提供借鉴。Pipe jacking is an important means in non-excavation construction.It can pass through the soil layer without damaging highways and buildings along the line.Combining with the engineering practice,some unfavorable problems,such as deviation of pipe body,large deformation of surrounding buildings or pipelines,are solved by applying thixotropic mud technology and stress release hole technology in the construction of large diameter drainage pipe jacking,which can provide a reference for similar projects.
