摘要： 地下管道竖向土压力的研究工作主要针对上埋式及沟埋式管道，对于隧洞式管道的研究相对较少，通过某具体工程实例的有限元分析，讨论穿过水塘这一特殊地质下顶管管道的土压力分布特点，得出了若干结论与建议，为该类型地下顶管管道的设计提供一定参考。

Abstract: Since Marston proposed his famous theory of soil pressure last century, various researchers performed wide and indepth researches on the vertical earth pressures acting on the underground pipes. However, majority of these researches are focused on either projective condition or trench condition. The earth pressures on the jacked underground pipes are rarely reported. This paper presents a case history of vertical pressures acting on a jacked pipe underneath a pond.
