【摘要】 混凝土裂缝的监测与检测工作对于基础设施的养护管理和性能评价具有重要意义,然而,传统监测技术难以感知新裂缝的产生,传统检测技术高度依赖检测人员的经验。针对以上问题,分别介绍了基于柔性导电涂料、长标距光纤光栅的混凝土裂缝监测技术及基于机器视觉的混凝土裂缝检测技术,分析其工作原理与应用案例,为混凝土裂缝监测技术和检测技术的研究提供参考。更多还原

【Abstract】 Crack monitoring and detection have importance sense to the maintenance management and performance evaluation of civil infrastructure. However, the conventional monitoring methods are difficult to perceive the generation of new cracks. Besides, the reliability of conventional detection methods are highly dependent on the inspectors’ experience. To solve these problems, the crack monitoring technology of flexible conductive paint, the crack detection technologies of long-scale fiber grating and computer vision based methods are discussed. Their principles and application cases are introduced to provide reference for the research of concrete crack monitoring and detection technologies.更多还原
