| 摘 要： | 通过对相邻深基坑开挖对周围地下管线位移场的三维有限元分析,探讨了基坑被动区加固、管线侧向加固和管线底部加固等3种保护管线的方式,分析了3种保护措施下管线水平、竖向位移的变化,讨论了3种加固方式对管线位移的控制效果,比较了3种加固方式的优缺点,研究表明,基坑被动区加固是一种较为合理的管线保护措施.

| Abstract: | On the basis of the analysis of the displacement field of buried pipeline around the two foundation pits,the protection measures of buried pipelines during excavation of two adjacent foundation pits are innovatively studied based on 3D FEM in this paper.Three methods used for the protection of buried pipelines,including the soil improvement of passive field,side area of pipelines and the bottom of the pipelines,are discussed.The efficiency and effectiveness of the methods are analyzed,along with comparison ... |
