Currently, the researchers have not yet conducted a detailed analysis of the anchor block stability and there exist shortcomings in the discriminatory formula for the slip length. On the basis of the existing computational formulas, the axial force formula for the pipeline was optimized considering expansion joints, and the axial force formula was proposed for downstream elbow pipe without considering the expansion joints. Furthermore, by analyzing axial thrust on pipelines in the context of considering or not considering the expansion joints and comparing the concrete amount of the anchor block under all conditions, the anchor block of the buried steel pipe was found to have the minimum amount of concrete used in the context of not considering the expansion joints and under certain condition, which can provide a reference for future research and design work.

针对现有研究成果缺少详细分析镇墩稳定性、可滑移长度判别公式存在不足的问题,在现有计算公式基础上,优化设置伸缩节情况下管道轴向力公式,提出了弯管下游轴向力和不设置伸缩节情况下轴向力公式,分析了设置伸缩节与未设置伸缩节情况下管道轴向推力及各条件下镇墩砼量比较,得到在一定条件下不设置伸缩节的埋地钢管镇墩砼量最省,可为今后的研究设计工作提供参考。

针对现有研究成果缺少详细分析镇墩稳定性、可滑移长度判别公式存在不足的问题,在现有计算公式基础上,优化设置伸缩节情况下管道轴向力公式,提出了弯管下游轴向力和不设置伸缩节情况下轴向力公式,分析了设置伸缩节与未设置伸缩节情况下管道轴向推力及各条件下镇墩砼量比较,得到在一定条件下不设置伸缩节的埋地钢管镇墩砼量最省,可为今后的研究设计工作提供参考。

Currently, the researchers have not yet conducted a detailed analysis of the anchor block stability and there exist shortcomings in the discriminatory formula for the slip length. On the basis of the existing computational formulas, the axial force formula for the pipeline was optimized considering expansion joints, and the axial force formula was proposed for downstream elbow pipe without considering the expansion joints. Furthermore, by analyzing axial thrust on pipelines in the context of considering or not considering the expansion joints and comparing the concrete amount of the anchor block under all conditions, the anchor block of the buried steel pipe was found to have the minimum amount of concrete used in the context of not considering the expansion joints and under certain condition, which can provide a reference for future research and design work.
