供热管道地震易损性分析
|
摘要
为了研究供热管道的地震易损性,采用有限元分析方法,建立了典型供热管道分析模型,选取典型地震波作为输入,通过数值模拟手段,对供热管道在地震作用下的应力反应进行了计算分析。基于三态破坏准则对单体管道地震破坏概率进行了分析,给出了供热管道不同地震烈度下的破坏概率。根据管道破坏服从泊松分布的基本假定,对不同烈度下一定长度供热管道地震破坏处数进行了估计,同时与历史地震中管道震害经验统计结果进行了对比分析,初步评述了供热管道的抗震性能。
In order to study the seismic fragility of heat supply pipeline,the method of finite element analysis is adopted to develop a typical model of heat supply pipeline.Selecting some typical seismic waves,by means of numerical simulation,the earthquake response of heat supply pipeline is analyzed.Besides,based on a tristate failure criterion,the failure probability of a single pipe is analyzed and the failure probability of a heating supply system under different earthquake intensities is summarized.According to the assumption of Poisson distribution for pipe damage,the damage number of a certain length of heat supply pipeline is also estimated and compared with the statistical data of seismic damage of pipeline,and the aseismic performance of heat supply pipeline is preliminary evaluated.
