| 摘 要： | 本文以现行《公路柔性路面设计规范》为依据,推导出三届弹性体系轮间路表弯觉系数的逼近式,使三层弹性体系弯沉表达式中的无穷积分隐函式显示化,以利于计算式的求解并节省计算机求解的时间。本文还应用多元线性回归理论,推导并验证了四层,五层体系结构层轮间路表弯沉系数的逼近式,以适应当前铺筑多层次的高等级路面的需要。

| Abstract: | In this paper, based on the present "THE STANDARDS OF ROAD FLEXIBLE PAVEMENT DESIGN" (TJT 014, 1987) in China, the approximate formulas of the deflection coefficient are deduced and testified in systems of three, four and five elastic layers for the flexible payement structure by the linear regression theory, which can change the current formttlas of hidden function with infinite integral into the easily calculated formulas.It will provide basis for building high-class flexible pavements of many layers in the future. |
