【摘要】 针对目前用传统测试方法难以有效地对预应力筋的应力状态进行分布测试的现状,提出了采用基于普通光纤的螺旋缠绕式准分布光纤应变传感器进行测试的新方法,分析了其结构设计思想和传感原理,并对其传感特性进行了理论分析和试验研究。此传感系统的研究为预应力筋应力状态的准分布测试探索了一条新的解决途径。更多还原

【Abstract】 It is difficult to use conventional methods to monitor the distributed stress status of prestressed reinforcement.In this paper,the spiral winding optical fiber strain sensor is proposed as a new solution to monitoring distributed stress status.The thought of structure design and sensing theory are analyzed,and the sensing characteristics are theoretically and experimentally studied.The sensing system provides a new exploration into the quasi-distributed stress monitoring of prestressed reinforcement.更多还原
