在分析了现行设计规范中当量回弹模量计算公式缺陷的基础上,通过大量计算分析,以等效弯沉的原则,回归出了荷载作用半径为15cm的换算公式。修正后的新公式适用于天津地区石灰土与原状软土模量比小于8且石灰处理厚度大于20cm的路基顶当量回弹模量换算。
在分析瞭現行設計規範中噹量迴彈模量計算公式缺陷的基礎上,通過大量計算分析,以等效彎沉的原則,迴歸齣瞭荷載作用半徑為15cm的換算公式。脩正後的新公式適用于天津地區石灰土與原狀軟土模量比小于8且石灰處理厚度大于20cm的路基頂噹量迴彈模量換算。

The calculation method of equivalent modulus of elasticity in present cement concrete pave-ment design specification is improper. According to the analysis of great amount of computing data, the new calculation method of equivalent modulus of elasticity is established based on the principles of equiv-alent deflection whose load radius is 15cm. The new formula is suit for that the modulus ratio of lime to soft soil is less than 8 and soft soil and the treated thickness is more than 20cm.
