Title: | Unsaturated shear strength of a silty sand | Authors: | Schnellmann, Reto Rahardjo, Harianto Schneider, Hans R. |
Keywords: | DRNTU::Engineering::Civil engineering | Issue Date: | 2013 | Source: | Schnellmann, R., Rahardjo, H., & Schneider, H. R. (2013). Unsaturated shear strength of a silty sand. Engineering geology, 162, 88-96. | Series/Report no.: | Engineering geology | Abstract: | Series of single stage, consolidated drained direct shear tests under different net normal stresses and matric suctions were carried out to evaluate the unsaturated shear strength behavior of a silty sand. A back pressure shear box was used to measure and control pore-air and pore-water pressures. The experimental data show that matric suction increases shear strength of the soil significantly following a highly non-linear relationship. An increase in net normal stress results in a higher shear strength and the shearing behavior changes gradually from a peak shear strength followed by a strain-softening behavior to a strain-hardening behavior. A comparison between experimental shear strength measurements and predicted unsaturated shear strength values was made and the results are presented in the paper. | URI: | https://hdl.handle.net/10356/103041 http://hdl.handle.net/10220/16897 |
