倒塌结构的检测鉴定方法研究及实例分析

Research and case analysis on detection and identification method of collapsed structure

倒塌结构的检测鉴定具有现场情况复杂、关键性取样困难和试样有限、结构变形和损伤的时序性和分类不易确定等特点,常规的结构检测鉴定方法难以有效解决倒塌结构检测鉴定中所遇到的问题。以故障树分析理论为基础,针对倒塌结构检测鉴定工程的特点,建立了倒塌结构检测鉴定故障树模型,提出和制定了倒塌结构的检测鉴定方法和流程。以某倒塌结构的检测鉴定为例,对所提出的检测鉴定方法和流程进行了分析和应用,以期为倒塌结构的检测鉴定提供方法论和实践意义上的参考。

The detection and identification of collapsed structures has the characteristics of complex site conditions, critical sampling difficulties, limited samples, and the difficulty for determining the timing and classification of structural deformation and damage. Conventional structure detection and identification methods cannot effectively solve the problems encountered in the detection and identification of collapsed structures. Based on the theory of fault tree analysis and according to the characteristics of the collapsed structure detection and identification project, a fault tree model for the collapsed structure detection and identification was established, and the methods and procedures of the collapsed structure detection and identification were proposed and formulated. Taking the detection and identification of a collapsed structure as an example, the proposed detection and identification methods and procedures were analyzed and applied, hoping to provide a methodological and practical reference for the detection and identification of collapsed structures.
