对英国现行的砌体拱桥荷载评估方法进行了评介。本文考虑了评估程序的标准，并检查了最近大规模试验方案的结果，以及这些方案提供的关于典型故障机制的信息。介绍了用于承载能力评估的每一种分析方法的背景。这四种方法分别是改进型军事工程实验装置(MEXE)法、钉扎弹性法、机理法和裂纹-弹性法。考虑了不同方法的数据要求。每一种方法都是根据选定的标准和就其是否适合进行评估而得出的结论进行判断的。本文排除了对条件因素的任何直接考虑。(A)
A critical review of current UK methods of masonry arch bridge load assessment is presented. The paper considers the criteria for assessment procedures and examines the results of recent large-scale experimental programmes, and the information these give on typical failure mechanisms. THe background to each of the methods of analysis which are being used for assessment of load carrying capacity are presented. These being the modified Military Engineering Experimental Establishment (MEXE), pinned-elastic, mechanism and cracking-elastic methods. The data requirements for the different methods are considered. Each method is judged against the selected criteria and conclusions drawn on their suitability for assessments. This paper excludes any direct consideration of the condition factor. (A)
