Study On Buried Pipeline Deformation Effect Caused By Tunneling

To study and solve adjacent environment effect caused by tunneling construction, especially in Shenyang, tunneling increase, the inbuilt time of buried pipeline long considerably, distribution complicated and the amount enormous, deficient in related technique data, paper study the ground deformation and the buried pipeline deformation for shield tunneling construction, combining test and measured ground surface and buried pipeline deformation in ShenyangPaper analyzes the factor of adjacent environment effect by shield tunneling construction, and discusses the measure to control deformation, and summarizes the computer means in cross section and vertical section.According the geological features of Shenyang, paper calculate the parameters of empirical formula for deformation, fix the capability to load of gas cast iron buried pipeline. Against the demand of project, paper put forward effective monitor program and obtain the rule of ground deformation and the effected range of buried pipeline for shield tunneling construction., meanwhile, certified the accuracy of empirical formula and the justifiability of monitoring value, and recommended to improve monitoring value of pipeline.By analyzing the effects of buried pipeline safety and security distinguish factor, paper proposed pipeline protection measures for the follow-up project to provide the design and implementation of reference.
