有许多不同的工具可用于评估砌体拱桥：实验公式、二维模型和有限元模型以及离散元模型（2D 和 3D）。由于拱门的复杂行为以及无法确定拱门和这些古建筑的填充物的材料特性，对不同的模型做出了许多不同的假设。到目前为止，还没有一个普遍接受的评估方法。本研究涵盖了一些二维评估工具的比较。基于案例研究对三个模型进行了比较：Ring、Archie-M 和弹塑性模型。结论是，每种模型都有优点和缺点。因此，无法说明应该首选哪种模型。关键词: 砌体拱桥, 评估方法, 倒塌荷载, 对比研究, 环, Archie-M, 弹塑性模型
A lot of different tools are available for the assessment of masonry arch bridges:experimental formulae,2D-models and finite-element models and discrete-element models (2D as well as 3D) . Due to the complex behaviour of the arches and the disability of determine the material properties of the arch and the infill of these ancient constructions, many different suppositions have been made for the different models. Until now there is not yet a generally accepted method for assessment. This study covers a comparison of some 2D assessment tools. Three models are compared based on a case study: Ring, Archie-M and an elasto-plastic model. It is concluded that every model has advantages and disadvantages. Thus it cannot be stated which model should be preferred. Key–Words: Masonry arch bridge, assessment methods, collapse load, comparison study, Ring, Archie-M, elastoplastic model
