摘　　要：对直径为1.5m的小孔径螺旋波纹钢管涵洞进行现场测试,用有限元软件对管周和轴向测试数据进行分析,并将分析结果与现场涵洞的实际变形情况进行对比。结果表明:螺旋波纹管波谷、波峰的切向应变差值与所处位置基本无关;车辆在路面行驶时,螺旋波纹管波峰、波谷出现的都是拉应变。该研究为国内螺旋波纹钢圆管涵洞的使用和分析提供了依据。Through the field test of spiral corrugated steel pipe culvert with diameter of 1.5 m, the finite element software was used to analyze the tube and axial test data, and the results of the analysis were compared with the actual deformation of the culvert. The results show that the tangential strain difference of the wave crests of the spiral corrugated pipe is basically independent of the position; when there are vehicles running on the road, the wave crests of the spiral corrugated pipe all show tension strain. This study provides the basis for the use and analysis of domestic spiral corrugated steel pipe culverts.
