摘要为研究多夹砂层结构玻璃钢夹砂管在荷载作用下的损伤进程及破坏机理，提出基于层间分离和渐进失效模型管涵数值计算模型和强度计算方法。采用双线性本构模型和B-K断裂能损伤演化准则的内聚力表面建模技术模拟层间分离，同时采用Rafiee材料刚度退化准则构建管涵结构的渐进失效计算模型，进而考虑夹砂层厚度和夹砂层层数等参数变化对结构强度的影响，明晰了管涵失效机理和各层应力变化规律。结果表明：荷载作用下裂缝首先出现在管壁外侧层间以及存在缺陷的薄弱位置，随后管涵经历层间分离、夹砂层破坏、缠绕层破坏等过程，直至发生屈曲失稳；增加单层夹砂层厚度对提高管涵强度有利，相同厚度的偶数加砂层管壁结构的力学性能明显优于奇数砂层结构。

Abstract：In order to study the damage process and destruction mechanism of glass fiber reinforced plastics pipes of a multi-clamp layer structure under load action, a numerical calculation model and strength calculation method based on the layer separation and progressive failure were proposed.The cohesive surface modeling technology, which adopted the bilinear structure model and B-K fracture energy damage evolution criterion, was used to simulate the separation between layers.A gradual failure calculation model for the pipe-culvert structure was constructed by the Rafiee material stiffness degradation criterion.The influences of parameters such as the sandwich thickness and sandwich layer number on structural strength were investigated.The failure mechanism of the tube culvert structure and the stress variation in each layer were clarified.Cracks under load first appear in the outer layer of the tube wall and at the weak position by defects, then the pipe-culvert structure undergoes the process of interlayer separation, sandwich layer destruction, winding layer destruction, etc., until the bukling instability occurs.

Key words： fiber reinforced polymer sand pipe interlayer separation progressive failure model sand thickness
