Investigation of Required Tensile Strength Predicted by Current Reinforced Soil Design Methodologies
Geosynthetic Reinforced Soil (GRS) is a promising technology that can be implemented in walls, culverts, rock fall barriers, and bridge abutments. Its use in walls and abutments is similar to Mechanically Stabilized Earth Walls (MSEW) reinforced with geosynthetics. Both GRS and MSEW are reinforced …

Geosynthetic Reinforced Soil: Numerical and Mathematical Analysis of Laboratory Triaxial Compression Tests
Geosynthetic reinforced soil (GRS) is a soil improvement technology in which closely spaced horizontal layers of geosynthetic are embedded in a soil mass to provide lateral support and increase strength. GRS is popular due to a relatively new application for bridge support, as well as long-standing …

Numerical Study and Load and Resistance Factor Design (LRFD) Calibration for Reinforced Soil Retaining Walls
… all transportation-related structures including reinforced soil retaining walls. The ultimate objective of this thesis work was to carry out reliability-based analysis for load and resistance factor design calibration for rupture and pullout limit states for steel and geosynthetic reinforced soil …

Performance of Improved Ground and Reinforced Soil Structures during Earthquakes – Case Studies and Numerical Analyses
… were located primarily in areas of poorest soil conditions, typically containing soft clays and silts and/or loose, liquefiable sands. Because the affected region is heavily developed with infrastructure and there is a preponderance of poor soils, a wide range of soil improvement measures …

The design and construction of a large plane strain apparatus for testing reinforced soil specimens
… between the reinforcement and surrounding soil to provide an improved basis for limit equilibrium design methods. The purpose of this study was to develop a plane strain triaxial apparatus and associated equipment to study the interaction of soil and reinforcement. The plane strain …

Analysis of reinforced embankments and foundations overlying soft soils
… the tensile strength and shear strength of soils has lead to many new applications of reinforced soil. The use of such reinforcing in embankments and foundations over weak soils is one of the most recent applications of this technology. The studies conducted were concerned with the …

The effect of reinforcing soil inclusion on offshore pipeline ploughs
… is extremely important to clearly understand the soil on the proposed pipeline route to accurately design the trench being excavated for the use of a pipeline. There are many types of soil which a plough could encounter when being pulled along the seabed. Three of the most common soils encountered …

Centrifuge modelling of the behaviour of geosynthetic-reinforced soils above voids
Understanding the deformation mechanisms of soils and geosynthetics in response to the formation of a void below a geosynthetic-reinforced soil is crucial to provide efficient designs of geosynthetic-reinforced soil systems such as embankments and landfill liners. Centrifuge modelling of the soil …

Permeability characteristics of fibre-reinforced Perth sandy soil
Fibres are mixed with soils to enhance their strength and hydraulic characteristics. Fibre-mixed soils are often known as the fibre-reinforced soils. In the past, both systematically and randomly reinforced soils have been used widely in civil and geotechnical structures. Randomly reinforced-soils …

Experimental and numerical investigation into the Sand/Geotextile shear interaction behaviour
… applications, including the reinforcement of soils which is achieved by laying geotextile sheets horizontally to carry the induced horizontal stresses. The behaviour of such reinforced soil structures (e.g. retaining walls) is determined primarily by the shear interaction between the soil and …

New methods for <i>in situ </i>measurement of mechanical root-reinforcement on slopes
… of roots to the shear strength of the soil is however difficult to measure in situ. Existing methodologies are time-consuming and therefore not suitable to quantify spatial variability on the slope. Furthermore, some existing methods, for example large in situ shear box testing, can be …

Reliability analyses for foundation and soil reinforcement applications
… mechanically stabilized earth (MSE) walls and soil nail walls. The lognormal distribution is widely used to represent geotechnical parameters, such as pile resistance model bias, due to its non-negative property and mathematical simplicity. However, pile resistance bias data may exhibit …

Evaluating Performance of Hybrid Geosynthetic-Reinforced Retaining Walls
Geosynthetic-Reinforced Retaining (GRR) walls have been extensively used in highway projects. A novel GRR wall was proposed to mitigate the problems (e.g. high connection stress) resulting from the relatively large spacing of primary reinforcement. This new GRR wall has secondary reinforcement …

Enhancing the engineering properties of expansive soil using bagasse ash, bagasse fibre and hydrated lime
Expansive soils exhibit massive volume change against fluctuations of moisture content. Shrinkage and expansion of soil can commonly take place near the ground surface, where it is directly subjected to seasonal and environmental variations. Construction of civil engineering structures on expansive …
