美国标准的高速公路桥台设计与计算

Design and Calculation of Expressway Abutment according to American Standard

桥台设计与计算以高速公路实际项目工程应用为依托,根据项目的工程建设背景,详细介绍了美国标准下的桥台设计参数。通过对桥台所受各种荷载的取值分析,确立了基于美国桥台设计与计算标准下荷载组合的原则。在此基础上对桥台控制截面进行了配筋设计及验算,提出了钢筋混凝土桥台构件的验算过程及控制要求,总结了桥台设计的关键技术,为同类高速公路桥台的设计与计算提供了有益的理论根据和经验,可供同行参考。

The design and calculation of the abutment is based on the actual project engineering application of the expressway.According the engineering construction background of the project, the design parameters of the abutment under the American standard are introduced in detail.Through the analysis of various loads on the abutment, the principle of load combination based on the American standard for abutment design and calculation is established.On this basis, the reinforcement design and check calculation of the control section of the bridge abutment are carried out, the check calculation process and control requirements of the reinforced concrete bridge abutment components are put forward, and the key technology of the bridge abutment design is summarized, which is the basis for the design and calculation of the similar highway bridge abutment.It provides useful theoretical basis and experience for reference by peers.
