Abstract:
Based on the monitoring data from the weight-in-motion(WIM)system of the Beijing-Shanghai National Highway(Yi-Huai section), the probability distributions of the characteristic parameters, including the weight of heavy vehicles larger than 55 t, the vehicle separation distance, the axle load, the time interval between two vehicle heads, were statistically analyzed. The fatigue load spectrum of heavy vehicles and the standard fatigue vehicle model of the Beijing-Shanghai National Highway(YI-Huai section)were derived. The fatigue load spectrum and the standard fatigue vehicle models of sub-lane and non-lane were established, and the total weights of the proposed standard fatigue vehicle model were heavier than those of the national standard. The results indicate that the daily traffics of the Beijing-Shanghai National Highway(Yi-Huai section)are 3 657 vehicles, and the heavy transport characteristics are obvious. The vehicle weight obeys the generalized extreme value distribution; the separation distance obeys the Gamma distribution; the axial weights and the axial spacing obey the mixed Gauss distribution; the headway time interval obeys the Lognormal distribution. The proposed fatigue load spectrum and the standard fatigue vehicle models can be used as the references for the fatigue evaluation of real existing bridges.
