| 摘 要： | 为研究钢波纹管涵在低路堤荷载作用下的力学性能,依托泗许高速安徽淮北段一处试验涵,对荷载分别作用于超车道、行车道、应急车道情况下管涵的切向应变进行现场测试。试验数据表明：当荷载作用于不同车道时,钢波纹管切向应变不同,随着荷载的移动,波纹管不同断面同一角度的切向应变值不同但变化规律相似。试验结果可以为今后的钢波纹管涵洞设计和施工提供理论依据。

| Abstract: | To study the mechanical performance of corrugated steel culvert under vehicle loads in low embankment,this paper have field tests to research the tangential strains of corrugated steel culvert when loads act on overtaking lane,driving lane,emergency lane singly,relying on a test culvert of Sixu Highway during Anhui period.These test datas indicate that the tangential strains are different when the loads act on different lanes,and the test points of which are at the same angle in different sections have similar change pattern,though their values are different with test point of load changing.The test results can provide theoretical basis for design and construction of corrugated steel culvert in future. |
