| 摘 要： | 采用光纤应变测量仪对桥梁钢索的应力应变在载荷情况下的变化进行了实验研究。采用有机玻璃和φ０．８ｍｍ钢丝，设计并制作了单索面斜拉桥模型。在该桥梁模型上进行了模拟活载的线性加载实验，为斜拉桥索力及应力应变的检测提供了一种新测式方法。

| Abstract: | The strain_stress variation measuring experiments of steel_cable_stayed bridge model under loading condition were done by using fiber optic strain sensing instrument.The steel_cable_stayed bridge model was made of plastic and steel wire with diameter of 0.8mm.The strain variation was linear with the linear increase of the living load.A new strain testing method by use of fiber optic strain sensor for the steel_cable_stayed bridge model was provided. |
