不连续埋地管线在沉陷情况下的可靠度分析
|
摘要
运用响应面法对埋地不连续管线在沉陷位移、管线直径、管线壁厚以及接口轴向弹簧等随机变量下的可靠度进行分析,得到埋地不连续管线接口最大相对位移超过渗漏位移的失效概率及可靠度指标,为沉陷区埋地管线的设计积累经验。
The reliability of discontinuous buried pipeline under the random variables of subsidence displacement,pipeline diameter and interface axial spring was analyzed using response surface method,the failure probability of the largest relative displacement of discontinuous buried pipeline interface exceeding leak displacement and reliability index,which accumulated experiences for design of burying land pipeline in subsidence area.
