考虑位移协调的上埋式圆管涵设计方法
Design method for buried circular tube with consideration of displacement compatibility
-
摘要: 埋入式圆形涵管上的填土不但是荷载,也是涵管与土发生作用的介质,这种特性决定了圆管涵的工作性质。本文考虑了涵管结构与土的位移协调,提出了相应的涵管设计方法。结合现有规范方法和试验结果的比较分析,证实了本文方法的合理性。Abstract: The interaction of the buried circular tube with surrounding soil dominates over the performance of tube.With consideration of displacement compatibility a design method of the buried circular tube has been proposed in this paper. In order to verify this approach, some calculations are compared with three condified methods and laboratory test results.
