摘要
埋地管道应力分析的关键是模拟管道与土壤的相互作用。基于CAESAR II内置的由Liang-Chuan(L.C.)Peng和American Lifelines Alliance提出的土弹簧模型,阐述了两种土弹簧模型的理论基础,在此基础上分析了两种土弹簧模型的优缺点和适用性;对比了管径、土壤密度、内摩擦角、管道埋深、管道壁厚对两种土弹簧模型的影响。对于土弹簧的选用给出了科学的建议,对于开展埋地管道应力分析工作具有积极作用。
The key factor of buried pipe stress analysis is to simulate pipe-soil interaction. Based on soil spring models presented by Liang-Chuan （L.C.） Peng and American Lifelines Alliance built in CAESAR II, theoretical basis of both soil spring models were introduced. Their advantages, disadvantages and applicability were studied. In the study, effect of the pipe size, soil density, internal friction angle, buried depth of the pipe and pipe wall thickness on the soil spring models was investigated; as a result the suggestion on soil spring model selection was proposed.
