摘要
在介绍振弦式应变传感器工作原理的基础上,探讨了温度对应变测试的影响规律,提出了振弦式应变传感器在混凝土以及大气中温度影响修正实用公式,并成功应用于湖南益阳茅草街大桥施工控制的实践中,取得了良好的应用效果。
Based on introducing the principle of vibration wire strain sensor,the rules of temperature effect on the train testing are analyzed. Correction formulas of temperature effect of vibration wire strain sensor exposed to the air and buried in concrete are presented, which applied in the construction control of the bridge of MaoCaoJie in Nan County.
