Abstract:Compared with the traditional circular shield,the research on the influence of shield tunnel construction on pipeline deformation and soil settlement is relatively rare and of certain novelty. For the influence of quasi-rectangular-type shield tunnel construction on adjacent underground pipelines and soil settlement,the indoor shrinkage model test is adopted,normal pipelines,non-continuous pipelines,discontinuous damaged pipelines and soil settlement factors under four different depths are considered. The deformation law of the deformation of the underground pipeline and the settlement of the soil in the sand-soil layer under the vertical conditions of the tunnel and the tunnel are analyzed. The test results show that the settlement and deformation laws of several types of underground pipelines are consistent,and the tunnel axis is symmetrical,and the distribution is V type. The maximum settlement of the discontinuous pipeline is smaller than that of the continuous pipeline,and the settlement of both ends of the pipeline outside the tunnel width is larger than that of the continuous pipeline. The change trend of bending moment of discontinuous pipelines is more relaxed than that of continuous pipelines,and the maximum positive and negative moment of discontinuous pipeline is less than that of continuous pipeline;The negative bending moment of the discontinuous damaged pipeline changes greatly on both sides of the pipeline;The settlement of deep soil conforms to Gaussian distribution,and the maximum settlement of soil increases with the increase of soil depth.
