分布式光纤传感监测技术研究

Study on the distributed fiber sensing monitor technique

如何监测大坝混凝土结构的随机裂缝 ,常规仪器显得无能为力。近几年来 ,作者及其课题组开展了一系列室内实验和现场试验 ,提出了随机裂缝监测的分布式光纤传感技术 ,通过对这一方法进行评述 ,然后结合沙牌RCC拱坝二维模型实验 。

To monitor the random crack of the concrete dam structure with the ordinary instrument isn't effect. In recent years, a series laboratory experiment and field tests were finished by the author and his research group. The technology for monitoring the random crack was presented by using the distributed fiber sensing monitor technique. By commenting on this method, combining with the two dimensional model experiment of Shapai RCC arch dam, the research results of author are introduced partly here.
