| 摘 要： | 管土相互作用是影响埋地管道抗震性能的关键因素之一，分析管土相互作用是城市地下管道建设中面临的突出问题。在应用ADINA软件实现地下管道与土体融合有限元建模的基础上，通过定义管土接触来设定管土相互作用；介绍了管土接触设定、地震荷载加载时间函数、模型参数选择与求解步骤，并依据所建模型计算了埋地管道的变形和应力分布。根据计算结果，分析了管土相互作用对埋地管道抗震性能的影响，并给出了几点工程建议。

| Abstract: | Pipe-soil interaction is one of the primary factors in earthquake resistance of buried pipeline, and the analysis of pipe-soil interaction is the key of underground pipeline construction. On the basis of finite element modeling, pipe-soil contact is simulated by Boolean Body Operators, and pipe-soil interaction is defined by the pipe-soil Contact Control Operators in ADINA. Pipe-soil contact definition, time function of earthquake load, model preferences and solution are introduced. The distribution of displacement and stress on buried pipeline is calculated. In- fluence of pipe-soil interaction on earthquake resistance of buried pipeline is investigated based on the results of numerical simulation. Finally, some advice for earthquake lifeline engineering is proposed. |
