摘　　要：贝雷桥具有组件标准化、拆装速度快、架设方案灵活的特点。文中采用单跨、单车道的设计方案,利用三维实体单元建模和梁单元建模相结合的方法搭建贝雷桥模型,并在给定荷载条件下进行强度校核。结果表明,所设计的贝雷桥在给定载荷下的应力和变形符合要求,具有较好的安全性。The Bailey bridge has the characteristics of standardized components,fast disassembly and assembly and flexible erection.This paper carries out the design of Bailey bridge with single-span,single-lane style.The Bayley bridge model is built using the combination of 3D solid element modeling and beam element modeling,and the strength was checked under given load conditions.The results show that the stress and deformation of the designed Bailey bridge under a given load meet the requirements and have good safety.
