地下管线变形与破坏的实验与监测研究

Study on buried pipeline deformation and damage by experiment and monitoring

文章通过对取自现场的承插式煤气铸铁管在实验室进行加载实验,对管线的变形和受力状态进行研究,得到了管线变形曲率的极限值。并结合地铁盾构隧道施工的监测数据分析,研究了沈阳地区采用盾构隧道开挖方法所引起地表变形的一些规律和对地下管线变形的影响,并论证沈阳地区煤气管线变形监控值的合理性。

The field socket gas pipeline is taken make the loading experiment in order to study the deformation and force state of the pipelines and the limit value of the deformation curvature of the pipeline. The monitoring data from the shield tunnel construction are analyzed, the effect of shield tunneling on the deformation of ground surface and buried pipelines is studied, and the rationality of the deformation monitoring value of gas pipelines in the Shenyang area is discussed.
