| Abstract: | Wetting-drying cycle in expansive soil is studied by experiments,and the expansive soil is borrowed from construction site of widening alteration of Jiangsu No.222 provincial road.The experiments include direct shear test and unconfined compressive strength test.Through analyzing the experimental data,the change law of expansive soil with the strength of wetting-drying cycle is found out.The experiments can supply the reliable data for practical engineering. |

| Keywords: | expansive soil wetting-drying cycle direct shear unconfined compressive strength |
