摘　　要：文物木结构古建筑是一个国家文化的重要组成部分,代表着民族文化的自信与传承。然而由于长时间受到环境和人为侵蚀,木结构古建筑易遭到损坏。为更好地保存好木结构古建筑以及其代表的文化内涵,对其结构安全监测提出了迫切的需求,近年来对木结构古建筑的安全监测方法也得到了快速的发展。分别介绍了虚拟重建、红外热成像、地面激光雷达、超声波监测、光纤传感等技术的原理及在木结构古建筑监测中的应用,并总结了其各自的优势与劣势。针对木结构古建筑采光不足问题,总结了光导系统,尤其是光纤光导照明系统对自然光的引入,该类照明系统具有清洁、安全的特点,避免了烛火、电类照明系统为木结构古建筑带来的火灾风险。Heritage buildings are an important part of a country’s culture and represent the confidence and inheritance of national cul-ture.However,due to environmental and artificial erosion for a long time,wooden-structure ancient buildings are vulnerable to damage.In order to better preserve wooden-structure ancient buildings and the cultural connotations they represent,there is an urgent need for their structural safety monitoring.The safety monitoring methods for wooden-structure ancient buildings have been rapidly developed in recent years.The principles of virtual reconstruction,infrared thermal imaging,terrestrial LIDAR,ultrasonic monitoring,and fiber optic sensing technologies and their applications in wooden-structure ancient buildings are introduced,and their respective advantages and disadvantages are summarized.For the insufficient light in wooden-structure ancient buildings,the introduction of natural light by light guide system,especially by fiber optic light guide system is summarized,which has the characteristics of clean and safe,avoiding the fire risk from candle flame and electric lighting systems.
