Abstract

The dilative behavior of soils is found to be very important when analyzing the critical or ultimate states of granular soils. However, scant previous research work has been done to identify the dilative behavior of granular soils, and very few dilation angles of actual soils have been reported, especially in the low confining pressure range. In an effort to study the dilative behavior of granular soils, the authors performed a number of triaxial tests on various granular soils. Test results indicate that dilation angles are much higher than the theoretical values suggested in the literature. The authors verified the test results through laboratory work as well as through a finite difference method computer program. Results of the numerical analysis showed that predictions of stress-strain relationships of granular soils are obviously improved when actual dilation angles are applied.
