摘　　要：盖梁作为连接桥梁上部和下部结构的重要组成部分,其数据的准确计算对桥梁的结构安全极其重要。目前常用的钢筋混凝土盖梁,多采用桥梁通软件进行计算。对于市政地面桥的设计,在非机车道以及机动车道之间常布置绿化带,而桥梁通的横断面布置无法准确模拟实际的道路断面,通常将绿化带与非机动车道一并作为机动车道考虑,或将绿化带与非机动车道一并作为分隔带来考虑。文章结合工程实例,对上述两种计算情况进行了对比,并应用桥梁博士软件按照实际的桥面布置进行了计算分析。通过与桥梁通的计算结果进行比较,得出相应的结论,希望可以为今后桥梁设计者提供一定的参考依据。As an important component connecting the upper and lower structures of bridges,the accurate calculation of the data of the cap beam is extremely important for the structural safety of the bridge.The commonly used reinforced concrete cap beams are mostly calculated using the bridge beam software.For the design of municipal ground bridges,green belts are often arranged between non motor vehicle lanes and motor vehicle lanes,and the cross-sectional layout of the bridge cannot accurately simulate the actual road section.Usually,green belts and non motor vehicle lanes are considered as motor vehicle lanes together,or green belts and non motor vehicle lanes are considered as separation belts.The article combines engineering examples to compare the two calculation situations mentioned above,and applies the Bridge Doctor software to calculate and analyze according to the actual bridge deck layout.By comparing the calculation results with those of the bridge,corresponding conclusions can be drawn,hoping to provide certain reference basis for future bridge designers.
