水泥路面基层模量及厚度力学性能分析

Analysis of Modulus and Thickness Mechanics Performance of Cement Pavement Base Course

采用数值计算的方法对路面在不同基层模量及厚度时的受力性能、抗疲劳性能进行分析比较,得出提高基层的模量及增加基层的厚度可以明显改善路面的受力性能、提高路面的疲劳使用寿命,进一步指出基层模量的提高可以通过改变基层的级配组成来实现。

After analysis and comparison of the bearing performance and anti-fatigue performance of the modulus and thickness in the different base courses of the pavement by the numerical calculation method, it is given that the enhancement of the base course modulus and the increment of the base course thickness can obviously improve the bearing performance of the pavement, enhance the fatigue service life of the pavement, and it is further pointed out that the enhancement of the base course modulus can be realized by changing the gradation of the base course.
