摘要
在水工结构模型试验中 ,应用光纤传感检测技术检测结构随机裂缝 ,在国际上已经受到高度重视并开始开发应用。四川沙牌碾压混凝土拱坝整体结构模型随机裂缝检测的光纤传感试验表明 ,光纤传感碾压混凝土拱坝整体结构模型随机裂缝获得成功 ,捕捉到了开裂荷载及开裂位置 ,处理涂敷层后的单模光纤对开裂比较敏感 ,光纤的铺设工艺是一个重要技术环节 。
In the hydraulic structure model tests, the optical fiber sensing detection technology is applied to detect the stochastic cracks in the structure, which has been highly stressed in the world The optical fiber sensing test on the stochastic crack detection in integrity structure model for Shapai RCC arch dam has shown that it is successful It can gain the cracking load and positions The single optical fiber without coat is more sensitive to crack The optical fiber spread technology is a key technical link, which should be deeply studied
