摘　　要：从理论上和算法上分析了桥梁静荷载试验加载动过程的安全性问题,通过将荷载试验车辆加载位置比拟成广义点,使得车辆加载的动过程安全性问题转化为计算加载安全域的边界问题,以使计算工作量大大减少,同时得出了车辆实际的加载路径,为桥梁静荷载试验工作提供了参考。The article analyzes the security of dynamic loading process in bridge static load test from theory and algorithm, and changes the security of vehicle dynamic loading process into the calculation of safe loading area＇s boundary through assimilating vehicle＇s loading position in load test to generalized point, in order to make the calculation workload be largely reduced and gain the way of practical vehicle loading, which to offer a reference for bridge static load test.
