【Abstract】 Based on the characters of unit impulse(function and the technique of Fourier, a model on Eular-Bernoulli beam of the pipelines under random traffic loads was established.During the calculation to the displace of the pipeline,the damp of the pipelines was taken into account.And the preparatory analysis on the displace response of beam considering the dynamic parameter in the system of pipeline-soil was proceeded.So a simple and clear solution was provided for the research of the mechanical properties on the underground pipelines under the traffic loads.更多还原
