【摘要】：在公路桥涵设计时,汽车荷载分为车辆荷载和车道荷载两种形式,在《公路桥涵设计通用规范》(JTJ 021—89)中是要求应用车辆荷载对桥涵进行设计,而在《公路桥涵设计通用规范》(JTG D60—2004)中则是要求采用车道荷载对桥涵进行设计.为研究新旧规范中不同的汽车荷载形式对实际桥涵工程设计的影响,文章通过实际算例采用两种不同汽车荷载形式进行验算,发现两种不同荷载形式对实际桥涵的内力计算有一定的影响.同时研究了在不同参数变化下两种汽车荷载形式对实际桥涵的内力计算的影响.计算结果表明,车道荷载在桥梁设计中相比于车辆荷载更偏于安全.
[Abstract]:In the design of highway bridge and culvert, the vehicle load can be divided into two forms: vehicle load and driveway load. In the General Code for Highway Bridge and culvert Design (JTJ021-89), it is required to use vehicle loads to design bridges and culverts. JTG D60-2004). In order to study the influence of different vehicle load forms on the actual design of bridge and culvert, it is required to use lane load to design the bridge and culvert in order to study the influence of different vehicle load forms in the new and old codes. In this paper, two different vehicle load forms are used for checking calculation through practical examples. It is found that two different load forms have a certain influence on the calculation of the internal force of the actual bridge and culvert. At the same time, the influence of the two vehicle load forms on the calculation of the internal force of the actual bridge and culvert under different parameters is studied. Lane load is more safe than vehicle load in bridge design.
