为适应108国道霍州退沙至侯马凤城一级公路路面改造工程主线标高,轰轰河桥的桥面铺装方案拟由原设计4 cm沥青混凝土+6 cm水泥混凝土改造为5 cm沥青混凝土+14 cm水泥混凝土。该方案经数值建模分析,结果表明,此桥按初拟方案计算,承载能力不满足设计要求。建议桥面铺装维持原设计,同时,桥梁两端与主线采用过渡段进行衔接。
To meet the 108 State Road Huoju back to Houma Fengcheng a highway pavement elevation project main line, the Hongqiao bridge deck pavement plan from the original design of 4 cm asphalt concrete +6 cm cement into 5 cm asphalt concrete + 14 cm cement concrete. The numerical analysis of the program, the results show that the bridge calculated according to the initial plan, carrying capacity does not meet the design requirements. It is recommended to maintain the original design of the deck pavement, at the same time, the two ends of the bridge should be connected with the main line through the transition section.
