摘要: 为深入研究玻璃钢夹砂管涵洞的力学特性,基于室内试验结果和工程实际,借助ABAQUS建立有限元分析模型,选取室内试验中两种工况的试验结果与数值模拟进行对比分析。结果表明,有侧限环向应变模拟结果与实测值非常接近,验证了数值模拟的正确性,无侧限埋地玻璃钢夹砂管道与室内有侧限试验模型结果具有相同的受力变化形式,当管涵的竖向变形达到直径的5%时,管顶上端填土高度为50 cm、70 cm条件下对应的极限承载力分别为66 t和71 t,为玻璃钢夹砂管涵的公路推广应用提供了重要的理论基础。

Abstract: In order to study the mechanical properties of FRPM pipes, based on laboratory model test results and engineering practice, the finite element analysis model is established by means of ABAQUS, and the test results of two kinds of working conditions in laboratory test are compared with numerical simulation. The results show that the lateral confinement ring is very close to the simulation results and the measured value to the strain, verifying the correctness of the numerical simulation. No sand pipe and indoor results exhibit the same stress variation test model of unconfined buried FRPM pipe confined deformation. When it reaches a diameter of 5% vertical pipe culvert, ultimate bearing capacity of the corresponding upper pipe top filling height of 50 cm, and 70 cm were 66 t and 71 t, respectively providing and an important theoretical basis for the popularization and application of highway FRPM pipe culvert.

Key words: highway culvert, FRPM pipe, model test, strain, finite element analysis
