摘　　要：预应力水泥混凝土路面具有强度高、接缝少、不易出现病害和设计使用寿命长等优点。为降低造价、连续施工,提出斜张法双向预应力水泥混凝土路面的新概念。通过对斜张法双向预应力水泥混凝土路面关键设计参数的研究,提出了预应力值大小计算方法、斜向无黏结预应力筋的布置方法及U型板的设计方法,并针对试验路进行了初步设计。Prestressed cement concrete pavement has the advantage of high strength,less transverse joints,less diseases and long life of design.To reduce the construction cost and be capable of continuous construction,a new concept of two direction cross-tensioned prestressed cement concrete pavement is presented.Through the research on the key design parameters of two direction cross-tensioned prestressed cement concrete pavement,the calculation method of the value of presstress,the arrangement methods of unbon-ded prestressed steel strand and the design method of U plate are given,moreover,a preliminary design of test road is carried out.
