摘要
为了探求FRP(fiber reinforced polymer)复合管涵结构的承载性能,文章进行了FRP复合管涵室外原型堆载试验,并采用三维有限元数值仿真技术,分析研究了FRP复合管涵结构的承载性能,采用ADINA软件分析了管涵结构与土之间的相互作用问题及其承载性能。试验结果与仿真分析结果对比分析表明FRP复合涵管具有高承载性能,同时试验结果验证了数值仿真结果的可靠性。
Focused on the bearing capacity of fiber reinforced polymer（FRP） composite culvert structure,the field load test is carried out and 3D finite element numerical simulation is adopted in this paper.The interaction between the culvert structure and soil and the bearing capacity of the structure are analyzed by the software ADINA.The comparison of the results of field test with those of numerical simulation shows that FRP composite culvert structure has high bearing capacity,and that the numerical simulations are reliable.
