砌体拱桥承载能力的评估传统上采用军事工程实验机构（MEXE）方法（或其修改版本）进行，该方法源于理想化的弹性结构建模。在过去25年中出现的替代技术补充了这一方法。这些技术突出了MEXE方法的一些明显缺点。本文提出了一个完整的推导的基本方程发表的Pippard，这是用来支持MEXE方法。这些方程进行了研究，在光的感知的缺点的方法和扩展到目前的新方程，可能会被用于更一般的应用。得出的结论对评估工程师有一定的参考价值。
The assessment of the load-carrying capacity of a masonry arch bridge has traditionally been undertaken using the Military Engineering Experimental Establishment (MEXE) method (or a modified version of this), which has its roots in idealised elastic structural modelling. This method has been supplemented by alternative techniques which have emerged over the last 25 years. These techniques have highlighted some apparent shortcomings of the MEXE method. The present paper presents a full derivation of the fundamental equations published by Pippard, which were used to underpin the MEXE method. These equations are studied in the light of the perceived shortcomings of the method and extended to present new equations that might be used for more general application. Conclusions are presented that will be useful to the assessing engineer.
