摘要
针对混凝土路面的力学分析通常采用弹性半空间地基模型,考虑到预应力混凝土路面的特点,采用板底摩阻力的迭代处理模型和多向影射无界元,提出用有限元—无界元耦合的方法计算预应力混凝土路面的应力和变形。计算结果表明分析模型是正确的,新计算方法具有结点数目少、精度高、便于网格自动形成等特点。
With considerations of structural characteristics, the finite infinite element method is suggest?ed to calculate the stress and deformation of prestressed concrete pavement on elastic semi-space foundation. Based on the iteration model of friction force at slab bottom and multiple direction mapped infinite element, a finite element-infinite element coupling method is proposed for the calculation of stresses and deformation of the pavement. Results of calculations indicate that the method proposed in this paper has advantages of fewer nodes, higher accuracy, automatic mesh formation, and is correct.
