Analysis of wind direction and wind speed for HongKong-Zhuhai-Macao Bridge vehicle anti-skid under different weather conditions
Taking the main bridge project of HongKong-Zhuhai-Macao Bridge(HZMB),the longest cross-sea bridge in the world(divided into two sections,A and B),as the research object,based on the vehicle skid model to estimate the safe speed thresholds without side-slip under sunny and rainy days,wind force of 1 to 17,and a va-riety of wind angles,we have analyzed the trend of the change of the safe speeds with the wind angle,the wind force,and the sunny and rainy conditions.The results show that the most unfavorable wind angle for safe driving is about 75°,and the most unfavorable wind angles for section A of the HZMB are 120°,150°,300°,and 330°,while the most unfavorable wind angles for section B are 15°,165°,195°,and 345°.Comprehensive analysis of the wind direction and wind speed data from the representative stations for meteorological observation of the Bridge shows that the high risk season for vehicle sideslip on section A of the HZMB is summer,with August being the high-risk month;the high-risk season for section B is summer,with July being the high-risk month,and the risk indicator for section B is greater than that for section A.
