摘要
基于单位脉冲(函数属性以及傅里叶级数技术,建立了随机交通荷载下管道的Eular-Bernoulli弹性地基梁受力模型对管道的位移响应进行了解析计算,模型中考虑了管道所受的阻尼,并进一步探讨了考虑管土系统动态参数特性时求解梁响应的解析算法,从而为地下管道受载荷作用下的力学性状研究提供了简捷、明析的解题方法。
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.
