摘　　要：为了探究高速公路中既有小跨径实心板桥混凝土现浇层厚度对桥梁受力性能的影响,依托济青高速公路改扩建工程,以5 m钢筋混凝土简支板桥为例,计算分析了混凝土现烧层从10~20 cm变化时实心板和铰缝的受力以及各片板跨中挠度的变化情况。In order to explore the influence of the thickness of cast-in-situ concrete layer of small span and solid slab bridge on the highway's mechanical performance,relying on the reconstruction and expansion project of Jiqing Expressway,the 5m reinforced concrete simply supported slab bridge is taken as an example to calculate and analyze the concrete.The force of the solid plate and the joint joint when the cast-in-place layer changes from 10cm to 20cm and the variation of the deflection of each plate.
