| 摘 要： | 针对预应力混凝土路面的特点,采用更符合工作状况的板底摩阻力的迭代处理模型,为合理反映无穷远处的位移为零而采用多向映射无界元,提出了用有限元–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,该研究对预应力混凝土路面的设计与施工具有一定的参考价值。

| Abstract: | The method of the finite-infinite element is suggested to calculate the stress and deformation of prestressed concrete pavement according to its structural characteristics. The iteration model of friction force at slab bottom is adopted,which is coincident much more with the working condition of PCP than the others before. Multi-direction mapped infinite element is adopted to reflect that zero displacement in infinite. The calculating results show that the analytical model is correct. The investigation is valuable for the design and construction of prestressed concrete pavement. |
