高速公路钢波纹管涵洞工程应用及其应变光测技术研究

主要介绍了钢波纹管涵洞在南京长江第四大桥北接线高速公路路基工程中的首次应用。现场实际应用结果表明，钢波纹管涵洞具有良好的路用结构适应性，施工简便，工期短；现场应变光测测试结果表明，在软土地基路段修筑钢波纹管涵洞充分利用了钢材的延展性，能够解决不均匀沉降问题。...

Summary:主要介绍了钢波纹管涵洞在南京长江第四大桥北接线高速公路路基工程中的首次应用。现场实际应用结果表明，钢波纹管涵洞具有良好的路用结构适应性，施工简便，工期短；现场应变光测测试结果表明，在软土地基路段修筑钢波纹管涵洞充分利用了钢材的延展性，能够解决不均匀沉降问题。
Bibliography:Two corrugated steel pipe culverts were chosen in north connection highway project of the Fourth Nanjing Yangtze River Bridge. From testing the strain conditions of corrugated steel pipe culvert under different soil fill heights, the fiber Bragg grating sensors were set in the inner or outer of corrugated steel pipe culverts. Corrugated steel pipe culvert has the capacity of larger deformation. So in the soft soil area, using its good ductility can solve the problem of uneven settlement.
