Characterization of a geosynthetic is necessary for its effective use in various field application of reinforced soil structure. In this paper, a new type of geosynthetic has been evaluated for its interaction properties for different backfill soils using direct shear device. The test results are compared based on the type of soils, inclusions, and interface mechanical properties. Three backfil...

The laboratory tests for measuring the effects of small strain to the shear strength and maximum stiffness development of post-cyclic degradation of hemic peat are reviewed in this paper. A series of laboratory testing has been conducted to fulfil the objective of this research to study the post-cyclic behaviour of peat soil and focuses on the small strain characteristics. For this purpose, a n...

This paper presents a coupled elastoplastic constitutive model for predicting the hydraulic and stress-strain-strength behaviour of unsaturated soils. Hydraulic hysteresis in the water-retention behaviour is modeled as an elastoplastic process with the elastic region of the saturation degree. The effect of change in degree of saturation on the stress-strain-strength behaviour and the effect of ...

Abstract This paper presents the summary of experimental program to evaluate potential KOBM (Klockner Oxygen Blown Maxhutte) slag stabilize geogrid-reinforced subgrade soil in Suva, Fiji. is a by-product steel manufacturing process New Zealand. The standard California bearing ratio (CBR) laboratory tests were performed on samples with various combinations geogrid and slag, along other geotechni...

Abstract Expansive subgrade soil needs to be re-engineered enhance the load-bearing capacity as it lacks sustain traffic and pavement load. Although various chemical modification techniques have proven effective for stabilization, they are expensive unsustainable. Coronus aggregate material is an uplifted coralline deposit abundantly available in Pacific. The current study focuses on strength b...

Abstract Sedimentary soil is made up of deposits that are the consequence weathering rocks have already been deposited elsewhere by various natural processes, including water, wind, and others. A location with sedimentary Bili-bili Dam in South Sulawesi Province's Gowa Regency. at this quite abundant has not used general, so it can be investigated for its use, namely stability against influence...

a non-linear finite element model could be a useful tool in the development of a method of predicting soil pressure-sinkage behaviour, and can be used to investigate and analyze soil compaction. this study was undertaken to emphasize that the finite element method (fem) is a proper technique to model soil pressure-sinkage behaviour. for this purpose, the finite element method was used to model ...

The widespread availability of soft rocks and their increasing use as cheap rockfill material is adding more to geotechnical hazards because time-dependent granular decomposition causes significant damage to their mechanical properties. An experimental study was conducted through monotonic torsional shear tests on crushed soft rocks under fully saturated and dry conditions and compared with ana...

Most of the field problems in geotechnical engineering are in three dimensional state or close to a plane strain condition. Strength and deformation properties of soils in plane strain condition are considerably different from those in an axisymmetric condition. Many researchers have investigated the behaviour of soils under a plane strain condition. However, most of the previous studies have c...
