Abstract

The relevance of this work is due to the importance of identifying latent defects in building structures of reinforced concrete foundations. The results of the study of defects and damage to reinforced concrete structures are provided. It is proposed to use a telecommunication optical fiber of the G.652 standard as a sensor for identifying mechanical influences for long-haul objects. The optical fiber is placed directly inside a reinforced concrete foundation. As a result, we revealed dependences of the increase in the amount of additional optical losses arising in the fiber located in the concrete beam under varying mechanical stresses and deformations with increasing load. Based on the data obtained, two schemes have been proposed that make it possible to locate local latent defects in the structures of reinforced concrete foundations. New results of measuring the values of mechanical damage and deformation of concrete beams in real time when varying the properties of light passing through an optical fiber of the G.652 standard are obtained.

使用标准G.652光纤对钢筋混凝土基础中的结构进行无损检测

摘要

这项工作的相关性是由于识别钢筋混凝土基础建筑结构中潜在缺陷的重要性。提供了钢筋混凝土结构缺陷和损坏的研究结果。提出使用G.652标准的电信光纤作为用于识别对长途物体的机械影响的传感器。光纤直接放置在钢筋混凝土基础中。结果，我们发现了在变化的机械应力和随载荷增加而变形的情况下，位于混凝土梁中的光纤中所产生的附加光学损耗量增加的依赖性。根据获得的数据，提出了两种方案，可以在钢筋混凝土基础结构中定位局部潜在缺陷。
