This paper studies the temperature deformity size of the cement concrete pavement. First, it regards the cement concrete pavement as a 4side freely rectangle sheets on elastic foundation. When the temperature along the thickness direction in a concrete pavement is not identical, the deformity of the pavement is very similar to a rear sphere. The deflection formulae are deduced, the size of the pavement′s corner deformity is calculated, and the deformity of the pavement as gravity...

This paper studies the temperature deformity size of the cement concrete pavement. First, it regards the cement concrete pavement as a 4side freely rectangle sheets on elastic foundation. When the temperature along the thickness direction in a concrete pavement is not identical, the deformity of the pavement is very similar to a rear sphere. The deflection formulae are deduced, the size of the pavement′s corner deformity is calculated, and the deformity of the pavement as gravity and wheel load is studied. The roadbed settlement size is calculated in accordance with that the concrete pavement′s center cannot lose contact with roadbed. With equivalent method, the approximate elastic rebound modulus of the roadbed is deduced. The calculation result shows that in the structure of the cement concrete pavement, the exceptional hard roadbed is unfit for guaranteeing that the center of the pavement not lose contact with roadbed. This paper finally suggests defining a suitable volume of the elastic rebound modulus of the roadbed in the rules.

研究了水泥混凝土路面板温度变形的大小,视刚性路面板为自由矩形薄板,当温度沿板厚非均匀分布时,路面板变形后呈球面,据此得到挠度表达式;考虑变形后路面板在自重和车轮荷载作用下的变形,计算出由此产生的路基沉陷量;根据板中不发生脱空现象的条件,计算出板角处路基应有的沉陷量,采用等效法近似地得到路基顶面回弹模量值.计算结果表明,在刚性路面结构中,欲保证路面板不产生脱空,路基顶面回弹模量不宜过大,建议在规范中对其规定上限值.
