摘　　要：以九寨沟(川甘界)至绵阳高速公路平通互通E匝道大桥为工程依托,通过有限元实体模型计算,对比分析了钢箱组合梁和钢板组合梁的横向力学性能,技术对比表明:钢箱组合梁抗扭惯性矩大、应力冗余度高以及承灾性能好,适宜于山区复杂服役环境的桥梁建设。Based on the E ramp bridge in Jiuzhaigou（ Sichuan Gansu boundary） to Mianyang expressway,the transverse mechanical properties of steel box composite beams and steel plate composite beams are compared and analyzed by the finite element model calculation. The technical comparison shows that the steel box composite beams with large torsion moment,high stress redundancy and good disaster carrying capacity are suitable for bridge construction in mountainous complex service environment.

关 键 词：中小跨度 钢箱组合梁 钢板组合梁 力学行为
