Study on the effect of shield tunnel construction on underground pipeline deformation by experiment and monitoring.

摘要

The field socket gas pipeline is taken to 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.
