斜向预应力混凝土路面是一种新型路面型式。其特点是在水泥混凝土路面内布置双斜向预应力筋,使其在路面长度和宽度方向上均产生预应力,从而使路面在较长范围内不设置伸缩缝的无缝水泥混凝土路面。近年来已在收费广场,高速公路短路基以及超重超载地区进行了大面积推广应用,根据研究成果,本文提出了斜向预应力混凝土路面规范设计与对策设计2种设计方法,总结了斜向预应力混凝土路面的材料要求及施工工艺,并对其经济效益进行了分析。
Oblique prestressed concrete pavement is a new type of pavement. The utility model is characterized in that the double diagonal prestressing tendons are arranged in the cement concrete pavement so as to generate the prestressed force in the pavement length and the width direction so that the seamless cement concrete pavement with no expansion joints can be provided in the pavement within a relatively long range. In recent years, large-scale popularization and application have been carried out in toll plazas, expressway short-circuit foundations and overweight and overloaded areas. According to the research results, two design methods for the specification design and countermeasure design of inclined prestressed concrete pavement are proposed, Stress concrete pavement material requirements and construction technology, and its economic benefits were analyzed.
