摘要：

Municipal construction causes damage to nearby pipelines. Based on the Winkler foundation model, which simplified the pipeline as Euler-Bernoulli beams of variable stiffness, the transfer matrix method is proposed to analyze the performance of the pipeline according to the beam's element differential equation. This method is verified by comparing with analytic solutions for beam with constant stiffness section. Then it shows the influence of joint stiffness on the deflection and internal force of the pipelines. It's hoped that the work above can supply technical support and guidance to the design and construction of pipelines.
