| 摘 要： | 为研究砂土与海底管道的作用机制，验证计算模式，我们用细砂和原型管道进行了模型试验。对埋入土中的管道，主要进行了轴向摩阻力试验，并将试验结果与多种计算方法进行了比较。对半埋管道，首先进行了管道静置沉降试验，试验结果与国外有关资料进行了对照，并验证了以极限分析理论为基础建立的计算方法；其次进行了管道侧向阻力试验以及往复荷载作用下管道侧向阻力及沉降试验

| Abstract: | In order to investigate the mechanism of sand-pipelines interaction, the model tests on restraint of fine sand to pipelines are carried out. These tests are mainly on the outer face friction for buried pipelines and the results are compared with those from several evaluation methods. The settlement test and lateral resistance test under static and dymamic loads are conducted for unburied pipelines and the results are compared with those from OTC 4067 and Finite Difference Method based on the analytical solutions. |
