钢箱拱桥试验模型的设计

以罗浮山东江博罗大桥为实体桥，利用相似原理、方程分析法和量纲分析法，对该系杆拱桥进行相似分析，建立钢箱拱桥试验模型，再利用方程分析法，求弹性模量和密度需满足的条件，为碳纤维吊、系杆在拱桥中的推广应用提供了可靠的理论依据。

Test model design of steel box arched bridge

Taking Luofushan Dongjiang Boluo Bridge as the real bridge,using similarity principle,equation analysis method and dimensional similar theory,it carries on similarity analysis on the tied-arch bridge,establishes test model of steel box arched bridge,the requirements of elastic model and intenisity are worked out by adopting equation analysis method,which has provided reliable theoretical basis for the promoting and application of carbon fiber crane and tie on arched-bridge.
