| 摘 要： | 为分析波纹管涵洞冻胀下的受力机理,利用大型有限元软件对多年冻土地区采用的金属波纹管涵洞进行力学性能分析,具体分析了在底面两端产生不同的冻胀量时,换填厚度、壁厚、上部填土厚度对涵管受力性能的影响,提出了针对常用直径为1m的波纹管涵洞适用的结构形式;同时得出了金属波纹管本身具有较大的横向补偿位移的能力,可适应较大的变形和沉降要求.

| Abstract: | In order to analyze stress mechanics of corrugated pipe culvert on the condition of frost heaving,the mechanical property of metal corrugated pipe culvert in permafrost region is analyzed with large-scale finite element software.And by concretely analyzing the effect of soil displacement thickness,pipe wall thickness and upper soil displacement thickness on mechanical property of pipe culvert when the two ends of culverts occurs different degrees of frost heaving, the structural style suited for corrugated pipe culvert with the diameter of 1.0m in common use is put forward.At the same time,that the metal corrugated pipe has outstanding capacity of axial supplement displacement is educed,which can meet the demands of rather larger deformation and settlement. |
