| Abstract: | There is an intrinsic relation between the soil water characteristic curve the suction friction angle, and the microstructure of unsaturated soils. A formula of the suction friction angle is derived by using the soil water characteristic curve from the viewpoint of microstructure of unsaturated soils. The theorical results are in good agreement with test results. |
