摘要
高(河埠)界(子墩)高速公路改建工程全长110km,桥梁及支线上跨结构物较多。如果均加铺18cm,会导致桥梁静载增加过多、上跨桥净高不足等问题。文章针对起终点、净高不足的上跨桥及部分桥梁前后段采取10cm厚沥青混凝土面层过渡段进行特殊处理设计,以减少对原水泥面板的开挖量。
The transformation work of Highway Gaohebeng-Jiezidun covers a total length of 110km with pretty many bridges along the road and overpass structures at the secondary line. If the mad is generally repaved by 18cm, it will bring forth the problems such as too much dead load on the bridge and insufficient clear height between road and overpass. The article proposes the special treatment design of 10cm thick asphalt concrete at the transitional section to solve the problems above mentioned.
