Abstract:
|
The paper presents preliminary results on the shear strength properties and collapse response of a compacted low-density mixture of fine sand and clayey silt in a hollow cylinder apparatus. Shear strength tests at two different contrasting hydraulic states (as-compacted and saturated) have been performed at constant mean net stress and different Lode angles. The results have allowed defining the variation of the critical state line with Lode angle and matric suction. The collapse response on wetting has been studied under constant mean net stress (p = 200 kPa) and deviatoric stress (q = 200 kPa), and at different intermediate principal stresses. Selected test results have been interpreted with the Barcelona basic model, in which changes in the critical state line with Lode angle has been considered. |
