古建筑在长期的自然条件作用下结构材料性能一般都发生了恶化,有些甚至使用功能也发生改变,必然影响它们的受力性能,需对其安全性能进行分析评估。考虑到古建筑是文物,不能采用传统的破损或半破损评估方法的特性,给出了一种无损综合评估法用于解决这类问题,并以故宫午门城台为例,详细介绍了这种无损检测方法的过程,并对午门进行了结构安全性能评估。
Under the long-term natural conditions, the performance of ancient building materials has generally deteriorated. Some of the functions of the ancient buildings have been changed, which inevitably affect their performance. Therefore, their safety performance needs to be analyzed and evaluated. Taking into account the ancient buildings are artifacts, can not use the traditional characteristics of damaged or semi-damaged assessment methods, a non-destructive synthetic assessment method is proposed to solve such problems, and the Forbidden City Meridian Chengtai as an example, a detailed description of this A non-destructive testing method of the process, and carried out structural safety evaluation of Meridian.
