Accuracy versus simplicity of anisotropic clay models
(2014)This paper explores the simulative capabilities of a family of simple anisotropic clay models collectively named SANICLAY models. For this purpose, the paper highlights how specific constitutive ingredients provide accuracy ... -
Anisotropic sand model and fabric evolution until the critical state
(2014)This paper presents a simple anisotropic sand model within a recently proposed anisotropic critical state theory (ACST). The model adopts the SANISAND constitutive model platform and uses a fundamental ingredient of ACST, ... -
The effect of cracking on the response and design of diaphragm walls and adjacent buildings
(2015)The development of the bending moment corresponding to the maximum tensile stress the concrete accommodated (relatively low with reference to the capacity of the wall) produces cracking initiation. Despite the fact that ... -
Effect of spatial variability of soil properties on the stability and permanent seismic displacements of highway slopes
(2019)The effect of spatial variability of soil properties, slope inclination and excitation characteristics on the development of permanent displacements is investigated using random fields, created by the Local Average Subdivision ... -
Effect of yield surface shape on the simulated elasto-plastic response of cohesive soils
(2010)This paper presents a discussion on the effect of the selected yield surface shape on the simulated drained and undrained response of cohesive soils. The discussion is made possible by sequentially implementing two different ... -
Efficient numerical modeling of liquefaction-induced deformations of soil structures
(2008)A new numerical methodology is presented for the simulation of the non cohesive soil response under small, medium and large cyclic shear strains, with special interest given to liquefaction phenomena. The new methodology ... -
Failure mechanisms of landfills under dynamic loading
(2008)Seismic stability of above-ground landfills is an issue of extreme engineering interest, and the proper implementation of the corresponding analyses requires dealing with several uncertainties related mainly to the special ... -
Numerical analysis of the seismic response of sand passively stabilized against liquefaction
(2015)Passive stabilization is a new technique for mitigating the risk of seismic liquefaction in the non-cohesive foundation soil of existing structures. It consists of the low pressure injection (in the soil pores) of colloidal ... -
Permeation potential of colloidal silica for passive stabilization of liquefiable soils
(2015)Passive stabilization is a new ground improvement technique against liquefaction. It consists of the low pressure injection of colloidal silica in the pores of a liquefiable soil. After well-controlled time, colloidal ... -
Phenomenological simulation of the seismic response of ground stabilized with colloidal silica
(2014)Passive stabilization is a novel technique for mitigating the risk of seismic liquefaction in the non-cohesive foundation soil of existing structures. It entails the low-gradient injection of colloidal silica in the soil ... -
Response of pile groups in clays under lateral loading based on 3-D numerical experiments
(2010)The response of laterally loaded pile foundations may be significantly important in the design of structures for such loads. Although simplified numerical methods are reliable for evaluating the response of a single pile ... -
Response prediction for axially loaded pile groups in clays using 3D nonlinear analysis
(2005)The objective of this paper is to quantify the effect of the interaction between the piles of a group under axial loading in clayey soils. Three dimensional parametric nonlinear analysis was carried out for various pile ... -
Rheological properties of colloidal silica as a means for designing passive stabilization of liquefiable soils
(2015)Passive stabilization is a novel ground improvement technique for mitigating liquefaction at developed sites. It is based on the low-gradient (low pressure) injection in the soil pores of colloidal silica, an aqueous ... -
The sliding surface roughness effect on landslides: A statistical study
(2016)Spring-block models are a useful tool for modeling avalanche-like dynamics for catastrophic landslides. This paper examines the statistical behavior of the failure of a rock (or soil) slope taking into account the effect ... -
Variation of p-multipliers for pile groups in clayey soils
(2012)A common approach to assess the diverse response of the piles forming a pile group is the p-multipliers method. Although several studies have been occupied with the estimation of p-multipliers, usually assigned for pile ...
