摘　　要：结合河北承德某工程实际,对工程中涵洞选用FRPM管的标段进行车辆静载试验,以研究其受力状况,为实际工程做指导。FRPM管的受力状况与不同填土高度及荷载作用密切相关,为此依据现场试验所得管道受力特征,在平面应变条件下,采用ABAQUS建立的管-土相互作用模型对现场试验进行数值模拟,利用数值分析的方法,以减少传统试验在人力、物力上的耗费。研究结果表明,在最小填土0.5m,不同车辆荷载作用下,管涵最大变形为1.3mm,管涵受力较好;试验与模拟结果一致性较好,验证了所建模型的正确性。Combined with an engineering practice in Chengde,Hebei province,the vehicle static load tests were carried out to test the force conditions of FRPM pipe as buried culvert for guiding actual engineering. Its force conditions are closely related with different filling heights and loads. Therefore,on the basis of stress characters obtained by field measurement,under condition of plain strain,the Pipe-Soil interaction model of field tests is established by ABAQUS for numerical analysis in order to reduce numbers and manpower costs of traditional tests. The results show that the pipe culvert buried under the minimum 0. 5 m in soil. And,under different vehicle loads,the maximum deformation of the pipe culvert is 1. 3 mm,and the stress of the pipe culvert is good. By comparing the results of static load test and numerical simulation results,the validity of the model was proved.
