摘　　要：针对既有建筑幕墙安全性能在线评估这一技术难题，考虑到钢化玻璃突发自爆及面板坠落而影响城市公共安全这一现象，给出了采用光弹检测技术来检测钢化玻璃内部杂质及缺陷、采用振动测试技术来检测幕墙面板支承松动损伤状况的两种方法，为解决幕墙用钢化玻璃突发性自爆或面板松动脱落检测提出了一种新思路。阐述了该两种方法的检测原理、方法及设备，建立起了相关的检测手段及评估标准，从而实现现场方便、快速地评价建筑幕墙的安全性能。The safety evaluation of building curtain walls is a challenging task. In view of the spontaneous breakage or falling down of existing glass curtain wall threatening urban public safety, the paper provides a photoelastic test for detecting the impurities and defects of tempered glass, and vibration test for identifying the looseness and damages of curtain wall panel supporting, which are new ways for solving sudden spontaneous explosion of curtain wall tempering glass and looseness of the panel. It also states the detection principles, detection methods and equipments of two methods. The standards of detection means and evaluation should be established in order to achieve the evaluation of the building curtain wall safety performance conveniently and efficiently.
