| 摘 要： | 286t大件运输车直接通行某主跨为140m的钢筋混凝土箱型拱桥是不安全的,需通过计算分析采用多车配重方式过桥。结合挑战某大跨径混凝土拱桥承重极限的超重车配重过桥实例,阐述超重车采用特殊方式过桥的可行性,对于类似工程具有参考价值。

| Abstract: | It is dangerous if the 286-ton overweight vehicle crosses the reinforced concrete box arch bridge which has 140m main span directly without any measures.The method of multi-vehicle balance weight should be applied through computation and analysis for crossing bridge.Combining with an instance of an overweight vehicle tries to cross a long span concrete arch bridge,whose ultimate weight capacity is close to the weight of vehicle,by balance weight approach,the feasibility of overload vehicles cross bridge through special approach is expatiated on,which has reference value to similar engineering. |
