An elasto-plastic model to describe the undrained cyclic behavior of saturated sand with initial static shear
With the aim of simulating the behavior of saturated sand with initial static shear (i.e., sloped ground) undergoing undrained cyclic loading, which leads to liquefaction and large cyclic shear strain development, an elastoplastic constitutive model which can describe both monotonic and cyclic torsional shear behaviors of saturated sand under drained and/or undrained conditions is presented. It...
متن کاملBehavior of Granular Soils under Dry and Saturated Conditions in Cyclic Torsional Shear Tests
This paper presents results from drained cyclic torsional shear tests on Toyoura sand and a residual soil under dry and saturated conditions. The relationships of shear strain, z with shear stress, z ; normalized shear stress, z z / ; vertical strain, z ; and equivalent shear modulus, Geq are compared. The investigation of granular decomposition with respect to its influence o...
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 کاملmedium dense non-cemented carbonate sand under reversed cyclic loading
carbonate materials are mostly found in tropical areas, where exploiting gas and oil resources are of high concern. their unique behavior under shear loading first was recognised during oil resources investigations in the persian gulf. off-shore structures have been placed on carbonate soils which are highly crushable.during storms cyclic loading imposes on the bases of structures lied down on ...
متن کاملResponses 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...
