| 摘 要： | 通过对多处水泥混凝土路面板下脱空形态的试验研究,获得脱空区的形态分布规律,并据此对不同车辆荷载作用下板体内应力变化进行解析求解和使用寿命计算。结果表明,水泥混凝土路面板下脱空、超载车辆和重载车辆是造成水泥混凝土路面板早期断裂的重要因素。

| Abstract: | Through the experiment study on cavity form beneath cement concrete pavement slabs,the distributive regularity of cavity form is obtained in this paper.Accordingly the stress variation of road slabs under different vehicle loads is analyzed and its service life is calculated.The result suggests that the cavity beneath cement concrete pavement slabs and the vehicle overloading are the important factors in incipient fracture of cement concrete pavement slabs. |
