1前言随着我国铁路运输事业的发展,铁路机车、车辆的种类日益增加,我们在工作中经常要对各种机车、车辆荷载,特别是长大货物车辆对桥梁的影响进行计算,因此有必要建立桥梁竖向荷载数据库以便于使用。数据保存采用Access数据库,充分考虑各种荷载形式,可保存集中荷载与线性分布荷载,并考虑公路汽车标准活载的主车数量的不确定性及车辆间的可变间距。程序在MicrosoftWindows操作 1 Introduction With the development of railway transportation in our country, the types of railway locomotives and vehicles are increasing day by day. We often have to calculate the influence of various locomotives, vehicle loads, especially those that grow up on the bridge, in our work. Therefore, it is necessary Create a bridge vertical load database for ease of use. Data storage uses Access database, taking full account of various load forms, can save the concentrated load and linear distribution of load, and take into account the uncertainty of the number of main vehicles live and the variable spacing between vehicles.
