为了解决纤维增强聚合物计算弹性模量取值不准确的问题，提出一种通过环刚度计算纤维增强聚合物管廊弹性模量的方法，采用数值模拟分析纤维增强聚合物管廊特征点的变形量及变形规律，并在德阳市某浅埋纤维增强聚合物管廊工程进行静、动载荷验证试验。结果表明： 1)通过环刚度反算得出管材弹性模量的方法基本可行； 2)浅埋纤维增强聚合物管廊变形与回填质量的相关度较大，而与内部环形肋的相关性不明显； 3)采用数值模拟得出的管廊在静、动荷载作用下的变形量及变形规律与现场试验结果基本吻合。

A method of calculating the elastic modulus of a fiberreinforced polymer utility tunnel using ring stiffness is proposed to accurately select the value of elastic modulus of fiberreinforced polymers in calculations. Furthermore, the deformation and related law of characteristic points of the fiberreinforced polymer utility tunnel are examined via numerical simulation. Finally, static and dynamic load tests are conducted in a shallowburied fiberreinforced polymer utility tunnel in Deyang, China. The following results are obtained: (1) The pipe elastic modulus calculated using ring stiffness is essentially feasible. (2) The deformation of the shallowburied fiberreinforced polymer utility tunnel is closely related to the backfilling quality but does not exhibit a clear relationship with the internal annular rib. (3) The deformation and related law of the utility tunnel obtained through numerical simulation under static and dynamic loads are consistent with the field test results.
