桥梁结构应变电测技术探讨

Measurement Techniques of Bridge Structure Strain

各种新型现代化电测仪器不断涌现,大大提高了桥梁结构试验的测试精度及测试效率,使大规模桥梁结构试验成为可能。结合笔者的工作实践经验,总结桥梁应变电测技术,如电阻应变计选取等技巧,可为同行提供参考。

The new modern electrical measuring instrument continues to emerge, greatly improving the accu- racy and efficiency of the test for the bridge structure, which makes large-scale bridge structure test possible. Combining with the author＇s practical experience, the paper sums up the bridge strain electrical measurement technology such as resistance strain gauge selection technique, which can provide references for the peer.
