Geotechnical centrifuges have been seen to date principally as research machines. A role is now suggested in which centrifuges of modest size and cost can contribute usefully to the education and training of geotechnical engineers in college laboratories. One such machine, which has been used in teaching for 15 years, is described, and examples of the results of a series of simple demonstrations ...

Reliable in situ testing during soil exploration is of great help to geotechnical engineers in design considerations. This paper describes the theory and the laboratory test results for determination of the density of a sand with a quasi-static penetrometer by measuring its thermal conductivity. Effects of disturbance caused by the penetrometer have been studied. It is shown that it is possible ...

Tomography is the reconstruction of images from measurements of line integrals. It is used in a variety of scientific and technical applications. Advances in electronics and computers make the technique accessible to geotechnical engineering. The combination of penetration testing and tomographic reconstruction would result in a powerful site investigation tool.A tomographic software was ...

For the past five years or so Hall effect semiconductors have been increasingly used in the geotechnical engineering laboratories at the University of Surrey. They have been incorporated as sensing elements in local radial and axial strain measuring devices, for the small-strain instrumentation of triaxial specimens, and in small diameter boundary normal and shear stress cells. Triaxial internal ...

The effective porosity is a required parameter for the mass flow rate calculations in groundwater hydrogeology. It is also a useful parameter in geotechnical engineering. In this paper, a methodology based on the tracer analysis technique is proposed to measure the effective porosity of clays. A test apparatus was developed and operational conditions were optimized to measure the effective ...

Single soil – column studies were carried out to understand the influence o harmaceutical effluent (industrial type) on the physico – chemical behaviour and on the index and strength properties of five soils (two commercial and three natural soils) due to artificial contamination extending to nearly 250 days period. Two modes of operation, two HRTs and two concentrations of effluents, ...

The GEOBLOCK porous pavement system is a series of interlocking blocks designed to offer turf protection and load support in areas used by heavy vehicles. The blocks create a flexible structure bridge system within the topsoil layer to support and distribute concentrated loads. The system is used successfully for a wide range of applications, including emergency vehicle access lanes, auxiliary ...

A Tyre Aggregate (TA) is made from scrap/waste rubber tyres. Four types of tyre aggregates are classified, namely the coarse-grained, fine-grained, random and composite tyre aggregates. Applications of these tyre aggregates are varied, but they are often used as geomaterial fills and highway-pavement components. More recently, TA has found application in geoenvironmental engineering. This paper ...

A plate compactor is a very basic machine in construction machinery. It is used to compact soil, granite, and other materials, especially in roadway building, foundation establishing and other construction projects. It is a machine or mechanism used to reduce the size of material such as waste material or biomass through compaction. The plate compactor (vibratory rammer) has a large vibrating ...

Geotechnical engineering, as a general practice, has always struggled with quantifying the significant amount of variability that can be present at any given site. There may be variability present in field sampling methods, equipment, lab testing procedures, level of training of field personnel, or many other such factors. One particular problematic aspect of slope stability analysis is the ...

Background The benefits associated with performing 3D slope stability analyses were expounded by Dr. Del Fredlund in the 1970s.  Over the years a number of 3D methods of analysis have been researched. These methods have ranged from the method of columns to approaches based on variational calculus, and more recently, the use of dynamic programming. The interest in 3D slope stability analysis ...
