Abstract


Currently, the vehicle hit a bridge accidents have continued to increase , especially in today's large shaft material flow traffic loads, the vehicle hit the bridge of the potential risks growing. At present, at home and abroad axle collisions less than, the risks associated with analysis of theories and methods are not mature . Therefore , to carry out related research is very meaningful . In this paper, hit by a car double steel truss bridge road risk as the main object of study , the main tasks include the following aspects: ( 1 ) analysis of the causes of crashes and axle axle collision probability estimates for qualitative analysis . ( 2 ) the car hit double steel truss bridge road damage may classify risks and risk factors , and for the steel truss bridge hit by a car complex risk factors , this paper proposes using AHP Axle collision risk identification research . ( 3 ) describes the probability of structural failure probability and risk relationship , the use of structural failure probability calculation method - Monte Carlo method to estimate the probability of collision risk axles . ( 4 ) the loss of the bridge collision comprehensive classification, and to establish a calculation model for each type of loss , to realize the consequences of axles collision risk quantification estimates ( 5 ) describes Axle collision general evaluation methods and propose a suitable steel truss bridge hit by a car a risk assessment model - based on ALARP criteria axle collision risk matrix . ( 6 ) the use of the proposed theory and method to instantiate the Dongjiang River Bridge crash analysis, collision risk analysis axle application in practice to provide a reference .
