斜向预应力混凝土路面位移测试研究

Experimental Study on the Displacement of Inclined Prestressed Concrete Pavement

斜向预应力混凝土路面是近年来新兴的一种路面类型,板长一般可达120m^200m,由于其具有接缝少、承载能力高、耐久性强等优点,被常用于收费广场、超限监测站及重载道路。文章依托斜向预应力实体工程,开展了斜向预应力混凝土路面板的位移测试,试验结果表明:夏季中午温度最高时,混凝土板的位移约4mm,晚上温度较低时位移约1mm,该试验研究结果可为斜向预应力混凝土路面的设计提供参考。

The oblique prestressed concrete pavement is a new structure of pavement in recent years. Because of its advantages of less joint,high carrying capacity and durability,it has been used in Toll Plaza,overrun monitoring station and heavy haul road. The slab length of inclined prestressed concrete pavement can reach 120 ~ 200 meters. The displacement test of oblique prestressed concrete pavement slab is carried out based on inclined prestressed solid engineering. Test results show that when the temperature is highest in summer,the displacement of concrete slab is about 4mm,and the displacement is about 1mm at low temperature in the evening. The results of the test can provide references for the design of oblique prestressed concrete pavement.
