基于室内试验的公路FRPM管涵洞有限元分析
BASED ON LABORATORY TEST ABOUT FINITE ELEMENT ANALYSIS OF HIGHWAY FRPM PIPE CULVERT
摘要
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.关键词
