The geotechnical engineering properties of soil exhibit varied and uncertain behaviour due to the complex and imprecise physical processes associated with the formation of these materials (Jaksa, 1995). This is in contrast to most other civil engineering materials, such as steel, concrete and timber, which exhibit far greater homogeneity and isotropy. In order to cope with the complexity of geo...

The overall goal is to identify and understand the physical processes that shape and change coastal environments. Emphasis is on the application of remotely sensed signals that can be compared with in situ observations and assimilated within predictive models. In tidal flat environments, the major goals are to detect geotechnical properties (e.g., sediment strength), morphologic features (e.g.,...

This paper deals with the usefulness and feasibility of three-dimensional (3D) finite element analysis in geotechnical engineering practice. The usefulness of 3D analysis is illustrated through two examples. The feasibility of such analyses is then considered by reviewing some recent numerical developments, which allow large-scale analyses to be conducted using relatively modest computational m...

The paper describes some recent developments in the application of lower bound shakedown analysis to geotechnical problems. The theoretical basis of shakedown analysis is briefly reviewed along with the necessary finite element and optimization procedures. In terms of applications, the primary focus is on pavement design which is discussed in some detail.

stability of foundations near slopes is one of the important and complicated problems in geotechnical engineering, which has been investigated by various methods such as limit equilibrium, limit analysis, slip-line, finite element and discrete element. the complexity of this problem is resulted from the combination of two probable failures: foundation failure and overall slope failure. the curr...
