| 摘 要： | 文中依托泗许高速安徽段工程实例,对波纹板拱桥的应变特征进行了现场测试,得出了其在车辆荷载作用下切向应变变化规律.结果表明,在低路堤荷载作用下,拱桥8/8跨位置的切向应变情况较其他位置不同,应进行特殊考虑.

| Abstract: | The corrugated steel culvert or bridge has many advantages such as stable performance,convenient installation,shorter construction period,environmental-friendly,good durability,low requirements on the foundation,lower construction cost,so it can replace reinforced concrete or masonry bridge in highway construction.The corrugated steel pipe （plate） has been used in many programs successfully in our country and abroad,so it has much value for generalization.Relying on an engineering project of Sixu Highway during Anhui period,this paper has a test to research the strain of Corrugated steel arch bridge,and get the change pattern of tangential strain under vehicle load.The results indicate that tangential strain of 8/8 span is different from other test points under low embankment load,we should take more consideration. |
