... on the ultimate frictional resistance along the skirt. The drainage valve was sealed in the second series of tests, such that the evolution of the frictional resistance, reverse end bearing resistance, and suction on the bucket under sustained loading could be illustrated. Moreover, the critical sustained uplift...

... on the mobilisation of the suction during monotonic uplift. The present study conducts physical model tests and finite element analyses to simulate the installation and vertical uplift of the bucket foundation, aiming at quantitatively addressing the above uncertainties. Results from model tests and numerical...

..., and the non-linearity rose by increasing suction in the soil. Results of image processing obtained from top and side views of the models besides the recorded earth pressures showed that the volume of the failure wedge behind the wall and consequently the imposed force to the wall in active condition...

... is validated. In addition, it was found that matric suction has greater impact on the q_c than total vertical stress. The CPTs performed on clayey sand show that the cone tip resistance increases as the degree of saturation decreases under different hydraulic conditions. A correlation...

.... In this study, the research need for a laboratory model set-up with minimised boundary effects has been addressed by a large instrumented soil column, which could more closely represent environmentally stabilised soil. The current results depict the expected pattern for the variations of soil suction...
