摘　　要：根据实际施工需求及标准,对预应力混凝土路面开展设计,通过进行立模及滑动层铺设处理,测定出预应力损失比,完成对路面钢筋加固;采用多层级方式扩大承压范围,实现对多层级摊铺的处理,再对预应力筋进行张拉处理,采用封锚与伸缩缝处理实现施工。测试结果表明路面设计与施工效果得到了明显提升,具有较高实际应用价值。According to the actual construction requirements and standards,the prestressed concrete pavement is designed,and the prestress loss ratio is determined by laying the formwork and sliding layer to complete the reinforcement of the pavement reinforcement.The multi-level method is adopted to expand the bearing range,so as to realize the treatment of multi-level paving,and then the prestressed tendons are tensioned,and the construction is realized by sealing anchors and expansion joints.The test results show that the effect of pavement design and construction has been obviously improved,and it has high practical application value.
