Abstract EN
The construction of shield tunnels inevitably causes displacement of the surrounding soil and additional stress and deformation of the buried pipeline.
An energy solution for predicting the deformation of buried pipelines caused by tunneling is proposed in this study.
First, based on the uniform ground movement model, the interval of the free displacement field of soil around the pipeline induced by tunneling is calculated.
Then, we use the Pasternak model to establish the total potential energy equation of the tunnel-soil-pipeline interaction.
The final settlement interval of the pipeline is obtained by solving the numerical calculation program with MATLAB.
The calculation results of the energy solution are compared with the results of the centrifugal test and the reported theoretical solutions of Winkler and Pasternak, and then the applicability of the solution for predicting the pipeline response under different geotechnical conditions is verified.
Combined with an engineering case, the energy method calculation results, numerical simulation results, and measured results are compared to obtain the most unfavorable position of the pipeline caused by tunneling.
At the end of this study, the application steps of the proposed method in actual construction are summarized.
These steps are used to predict pipeline response in order to take protective measures.
