| Abstract: | In order to realize effective connection between the new and the existing subgrades in subgrade widening, the method of using lime-flyash-improved soil and geogrid for subgrade widening is put forward. Taking the subgrade widening project of coastal highway in Cangzhou as research subject, and based on the rock-soil-faced ANSYS Midas/GTS platform, the improvement effect of lime-flyash-improved soil and geogrid for subgrade widening is analyzed. The result shows that as a flexible reinforcement material, the geogrid improves effectively the mechanical properties of the widened subgrade. |
