结合扬州地区一条典型道路的相关参数对交通荷载的模拟公式进行拟合,采用带参数的正弦公式模拟交通荷载。利用有限元模拟软件ABAQUS并采用子程序DLOAD分别进行了二维和三维的模拟验证,在二维工况下验证了波动的荷载在道路各层次中传递的规律,并计算出了交通荷载的影响深度;在三维工况下验证了荷载的移动在空间上对道路各层次的动态变形的影响。结果表明,利用带参数的正弦公式模拟交通荷载是一种较合理的模拟方式。
結閤颺州地區一條典型道路的相關參數對交通荷載的模擬公式進行擬閤,採用帶參數的正絃公式模擬交通荷載。利用有限元模擬軟件ABAQUS併採用子程序DLOAD分彆進行瞭二維和三維的模擬驗證,在二維工況下驗證瞭波動的荷載在道路各層次中傳遞的規律,併計算齣瞭交通荷載的影響深度;在三維工況下驗證瞭荷載的移動在空間上對道路各層次的動態變形的影響。結果錶明,利用帶參數的正絃公式模擬交通荷載是一種較閤理的模擬方式。

By adopting sine formula with parameters in simulating the traffic loads ,the simulation formula was derived and then fitted by the application to the relative parameters of a typical highway in Yangzhou area .With the assistance of the finite element simulation software ABAQUS , simulation verifications were carried out by using its subroutine -DLOAD in both 2-D and 3-D .Under 2-D situation ,the load transfer laws of sine-wave was verified and the influence depth of the traffic loads was calculated .Furtherly ,under 3-D situation ,the impact that the moving loads poses on the deformation of road hierarchies was verified .Result reveals that the sine formula with parameters is a more suitable for-mula to simulate traffic loads .
