为了满足国民经济发展的运输要求,公路桥梁的建设规模越来越大,而超载超限的运输工具也越来越多,给桥梁的安全使用带来极大的威胁,而桥梁本身的病害问题,也是造成重车压垮桥梁事故的重要原因.本文将基于汽车荷载适应性的角度,在对重型运输工具设计参数调查分析的基础上,从侧面反映出桥梁车辆荷载设计的必要性,对桥梁的荷载设计进行详细探讨.
為瞭滿足國民經濟髮展的運輸要求,公路橋樑的建設規模越來越大,而超載超限的運輸工具也越來越多,給橋樑的安全使用帶來極大的威脅,而橋樑本身的病害問題,也是造成重車壓垮橋樑事故的重要原因.本文將基于汽車荷載適應性的角度,在對重型運輸工具設計參數調查分析的基礎上,從側麵反映齣橋樑車輛荷載設計的必要性,對橋樑的荷載設計進行詳細探討.
