Responses of Saturated Sand Surrounding A Bucket Foundations Under Horizontal Vibration Loading
In this paper we investigated the responses of saturated sand under horizontal vibration loading induced by a bucket foundation. It is shown that the saturated sand liquefies gradually since the vibration loading is applied on. The maximum displacement on the surface of sand layer occurs near the loading end and in this zone the sand is compressed and moves upwards. The liquefaction zone is dev...
متن کاملThe Behavior of Suction Bucket under Cyclic Loading in Saturated Lands
Numerical modeling was carried out to investigate the responses of suction bucket foundations under vertical cyclic loading. Numerical results were compared with centrifuge experiment results. Before the capacity of the model suction bucket to resist cyclic loading could be investigated, the static pullout capacities had to be determined. The buckets with different aspect ratio are investigated...
متن کاملEffects of Sand and Silica Fume on the Vibration Damping Behavior of Cement
The addition of sand to cement paste was found to degrade the vibration damping ability, as shown by decreases in both loss tangent and storage modulus under flexure. However, further addition of silica fume more than restored the vibration damping ability, due to the silica fume causing increases in both loss tangent and storage modulus. Silica fume increased the loss modulus of mortar by as m...
متن کاملDistribution of colloid particles onto interfaces in partially saturated sand.
Colloids have long been known to facilitate the transport of contaminants in soils, but few direct observations have been made of transport and retention in unsaturated porous media. Studies have typically been limited to evaluation of column breakthrough curves, resulting in differing and sometimes conflicting proposed retention mechanisms. We carried out pore scale visualization studies of co...
متن کاملElasticity of partially saturated frozen sand (short note)
Seasonal thawing and freezing of near-surface sediments significantly affect the interpretation of seismic reflection surveys and vertical seismic profiling, as well as activity on the surface. Permafrost covers much of the Earth’s colder regions and is also subject to periodic thawing and freezing. The significance of the regions with large seasonal temperature variations for exploration and e...
