| 摘 要： | 将笔者曾提出的搭板罩面方法用于处理板底脱空问题,通过与直接罩面法对比,分析搭板罩面法处理旧水泥混凝土路面板底脱空的效果,有限元计算表明搭板罩面法能有效地改善裂缝顶的剪应力集中,文中还针对这种处治方法的薄弱点提出了相应的改善措施,计算结果表明该法理论上是可行的。

| Abstract: | The cavity underneath cracked concrete pavement is treated with bridging slab and asphalt overlay which is brought forward by the authors.The effect of bridging slab and asphalt overlaying method is compared with asphalt overlay method by calculating. The FEM calculating results indicate that the sheer stress concentration at tip of the crack can be improved by bridging slab and asphalt overlaying method. Some improvement measures toward weak points of bridging slab and overlaying method are analyzed in this paper. It can be concluded from the calculation results that the bridging slab and asphalt overlaying method is feasible in theory. |
