摘要:
为研究新旧混凝土道面接缝处温度-荷载对机场道面板间力学性能的影响,基于Winkler地基模型,采用有限元方法建立了道面结构温度场计算模型.同时对华东地区某机场道面进行了重型落锤式弯沉测试,通过对比分析新旧道面板上不同位置处的弯沉、脱空判定值及传荷系数的变化规律,验证了计算模型的可靠性,进一步分析板底拉应力作用机理.结果表明:现场测试弯沉值考虑温度的影响,以保证对新旧道面板的板底脱空判定值和接缝传荷能力评价结果的可靠性; 新旧道面间接缝的传荷系数与温度呈较好的二次曲线关系; 随温度升高,在荷载作用下板底集中应力无法有效地释放,新道面的板底拉应力明显增大; 提高道面板弹性模量可增强接缝处新旧道面板间应力扩散传递,但也会增大板底拉应力,易导致道面板沿板底向板顶开裂破坏.
Abstract:
In order to study the mechanical properties of the joints between new and old concrete pavement slabs under temperature-load action, based on the Winkler foundation model, the temperature field calculation model of pavement structure was established by finite element method. At the same time, heavy drop weight deflection test was carried out on pavement of an airport in East China, the changes of deflection, void judgment value and load transfer coefficient at different positions between the old and new pavement slabs were compared and analyzed, which verified the reliability of the calculation model and further analyzed the mechanical mechanism of slab bottom tensile stress. The results showed that the influence of temperature should be taken into account when calculating the deflection value in field test. So as to ensure the reliability of the evaluation results of void judgment value and joint load transfer capacity of the old and new pavement slabs; The load transfer coefficient of the joints between the old and new pavement had a good quadratic curve relationship with the temperature; With the increase of temperature, the concentrated stress at the bottom of the slab could not be effectively released under the load, and the tensile stress at the bottom of the slab increased significantly; The stress diffusion can be enhanced at the joints by increasing the elastic modulus of the pavement slab, but it could also increase the tensile stress at the bottom of the slab, which was easy to cause the cracking failure of the slab from the bottom to top of the slab.
