| 摘 要： | 为准确分析埋地管道的管周应力状态，必须充分考虑管土相互作用的特性。在考虑管土变形协调的基础上，将上埋式管道管周土压力问题归结为求解重力场下二维弹性介质内嵌弹性圆环的孔洞应力集中问题，得到了管周应力与位移的分布函数,并对管道土压力的计算图式进行了简化，最后通过算例将本文结果与其他方法结果进行了比较。

| Abstract: | In order to analyze the stress state around the projecting buried pipe accurately, the pipe-soil interaction should be considered. Base on the condition of pipe-soil displacement harmony, the pipe-soil interaction boils down to a stress concentration problem of planar elastic medium embedded with an elastic circular tube in gravity field. The distribution functions of stress and displacement around pipe wall are obtained through elastic analysis, and the calculation model of the internal force of the pipe section is simplified. Finally, a case study is carried out, and the results are compared with several other calculation formula of soil pressure in buried pipe. |
