the proceedings contain 153 papers. the topics discussed include: a non-associated creep model for structured anisotropic clay (n-SAC);adaptive integration of hypoplasticity;an examination of strain space versus stress space for the formulation of elastoplastic constitutive models;application of discontinuity layout optimization to problems involving non-associative friction;influence of destructuration of soft clay on time-dependant settlements;modeling static liquefaction within multilaminate framework;on the differences between the Drucker-Prager criterion and exact implementation of the Mohr-Coulomb criterion in FEM calculations;simulation of mechanical behaviour of Toyoura sand using Severn trent constitutive model;time- and stress-compressibility of clays during primary consolidation;uncertainty and sensitivity analysis of laboratory test simulations using an elastoplastic model;and analysis of the stability of sheet pile walls using discontinuity layout optimization.
Dimensioning of driven stone columns on the basis of the existing methods may raise certain doubts. It is due to underestimation of their load capacity and overestimation of their settlement. the alternative solution ...

A new computational plasticity scheme for nonassociated frictional materials is presented. While general, it relies solely on well established concepts of associated plasticity. the new scheme is applied to some commo...

Finite element analysis of the penetration of a solid object into a soil layer is probably one of the most sophisticated and challenging problems in numerical analysis. In this study the Arbitrary Lagrangian- Eulerian...

Several large scale 3d finite element analyses for the design of offshore foundations have recently been carried out at NGI. the commercial software code Abaqus was used for parallel computation on an in-house compute...

Acomplex of numericalmethods was used for predicting the stability of the tailing dam in Norilsk industrial region (Northern Siberia). the carried out calculations include the calculation of the temperature condition...
详细信息
Evaluating the stress response of a constitutive relation of the rate type for a given strain increment can be seen as a time integration. the question whether explicit or implicit methods should be used for this inte...

While engineering expertise, professional recommendations and empiricisms play an important role in current tunnel and cavern design practice, the tremendous increase of computer power and the improvement of the user-...
详细信息
the construction process of diaphragm walls can lead to movements in the surrounding area that are seldom taken into account. However, these movements may be important in situations where soft soils dominate. In this ...
详细信息
Two families of the point-symmetric linear coupled consolidation models - differing in one boundary condition - are treated. the models are with space dimension one (oedometric), two (cylindrical) or three (spherical)...
