| 摘 要： | 由于顶管施工不可避免地对周围土体产生扰动,引起地层移动,从而威胁邻近地下管线的安全.文中以某地铁站出口市政过街通道矩形顶管施工为背景,通过分析矩形顶管施工时土体与地下管线的相互作用,探讨管线应力和位移的分布情况,对其破坏机理进行了总结,并阐述了相应的控制措施.

| Abstract: | Because pipe jacking inevitably results in disturbances of the surrounding soil, causing ground move- ment, thereby threatening the safety of nearby underground pipeline. Based on the rectangular pipe jacking con- struction of a subway station export municipal channel, the interaction between underground pipelines and soil is analyzed; the distributions of stresses and displacements of the pipeline are discussed; its failure mechanism is sum- marized, and the corresponding control measures are described. |
