ANALYSIS OF COUPLING RESPONSE OF PIPELINE-SOIL SYSTEM WITH CHANGING PARAMETERS UNDER TRAFFIC LOADS
-
摘要: 动力载荷作用下管土系统中的参数存在动态变化特征。在建立的交通荷载下管道的EularBernoulli弹性地基梁受力模型中，首先考虑了管土系统中参数随着空间变化时耦合响应的详细解析求解过程，再对系统参数随时间变化情况下的耦合响应计算提出了解析求解方法，从而为受载荷作用的下埋管道力学性状研究提供了简捷、明析的解题方法。Abstract: The parameters of the pipeline- soil system have the dynamic character under the impetus loads. So the Eular-Bernoulli elastic beam model under traffic loads is set up. Firstly, the analytic solution of the coupling response considering the changing parameters with the space is brought forward; and the analytic solution for the changing parameters with the time is put forward subsequently. So a compact and perspicuous method for the research on the mechanical behaviors of the underground pipelines under traffic loads is provided.
