采用花旗松胶合木作为芯材,玻璃纤维增强复合材料(GFRP)作为面层制备夹芯结构桥面板,在对花旗松胶合木芯材和 GFRP 开展基本力学性能试验研究的基础上,开展了 GFRP-花旗松胶合木夹芯梁的受弯性能试验,得出了其荷载-跨中挠度曲线与 GFRP 荷载-跨中应变曲线,并对抗弯刚度测试值与理论计算值进行了对比;针对某 GFRP-花旗松胶合木桥面板,提出了完整的结构设计流程,给出了桥面板的合理设计参数。研究结果表明:GFRP-花旗松胶合木桥面板应用于钢梁-复合材料桥面板组合桥梁结构较为可行。
採用花旂鬆膠閤木作為芯材,玻璃纖維增彊複閤材料(GFRP)作為麵層製備夾芯結構橋麵闆,在對花旂鬆膠閤木芯材和 GFRP 開展基本力學性能試驗研究的基礎上,開展瞭 GFRP-花旂鬆膠閤木夾芯樑的受彎性能試驗,得齣瞭其荷載-跨中撓度麯線與 GFRP 荷載-跨中應變麯線,併對抗彎剛度測試值與理論計算值進行瞭對比;針對某 GFRP-花旂鬆膠閤木橋麵闆,提齣瞭完整的結構設計流程,給齣瞭橋麵闆的閤理設計參數。研究結果錶明:GFRP-花旂鬆膠閤木橋麵闆應用于鋼樑-複閤材料橋麵闆組閤橋樑結構較為可行。

The bridge panel of sandwich structure was manufactured by using pseudotsuga taxifolia glulam as core materials and glass fiber reinforced polymer (GFRP) as surface course . The bending experiment of GFRP-pseudotsuga taxifolia glulam beam was carried out based on basic mechanical property of pseudotsuga taxifolia glulam core materials and GFRP .From the bending experiment ,the load-midspan deflection curve and GFRP load-midspan strain curve were got ,and the test value was compared with theoretical value of bending stiffness .It brought up a whole structured design process of a sandwich structure bridge deck , and gave the design parameter of bridge deck .The study results show that using GFRP-pseudotsuga taxifolia glulam bridge deck into girder-composite bridge panel is feasible .
