摘要
在分析面板裂缝成因的基础上,根据弹性力学理论及结构分析提出沥青混凝土面板与普通混凝土面板组合的双层面板结构,从而使上下层面板解除约束,释放变形,减小面板拉应力,实现面板抗裂变形与防渗功能分割,通过理论分析及数值计算,验证了此措施的可行性。
Based on analysis the causes of concrete face slab cracks, according to the elastic force scientific theory and the structure analysis to propose the Two-layered slab structure combined by asphalt concrete face slab and the plain concrete face slab. This method releases the distorts and the restraint, reduces the concrete face slab tensile stress, realizes the division function of the slab anti-crack and the anti-seepage.The theoretical analysis and the value computation confirms the measure feasibility.
