3D Numerical Analysis Of Soil Nailing In Sedimentary Soil With Vertical Inclusions
In this case study of a soil nail retaining wall, the measured horizontal displacement is of the order of 0.023% H, where H is the excavation depth, while the two-dimensional Finite Element Method (FEM) analysis suggests horizontal displacements of the order of at least 0.5% H. This study aims to understand which parameters influence such […]
Mechanically Stabilized Wall (Msw) With Geogrids As Complement Of Partially Executed Anchored Wall
This article presents the case study of Wall C11 of Lot 1 in the ringroads of Caraguatatuba and São Sebastião job site, whose original design consists of an anchored retaining wall with a concrete face supported on root piles. At the time of its interruption, only a part of the job had been executed. The […]
Behavior Of Clayey Soil Treated With Nano Magnesium Oxide Material
Clayey soils are spread in many countries and require significant improvement. Recently, nanomaterial have been entered to the geotechnical research as a treatment material. Current study utilized magnesium oxide (MgO) as an additive to enhance swelling potential, compressibility characteristics, and index properties of clayey soil from Mosul city using different content of nano-MgO and under […]
Influence Of Industrial Effluent Treatment Ettringite On The Compressive And Tensile Strength And Microstructure Of Soil-Cement Mixtures
It is increasingly important to find solutions for the problem of the aluminium anodising industry which generates a large amount of acid and alkaline wastewater, composed of high amounts of phosphates, sulphates, nitrates and aluminium. The sulphate removal trough ettringite precipitation is a simple process and involves a low-cost operating. The ettringite can be also […]
Influence Of The Addition Of Carbon Nanotube On The Physical Behavior Of A Lateritic Soil From The Southwest Amazon
In this work we evaluate the physical-mechanical behavior of lateritic soil with addition of carbon nanotubes. The soil was collected in a commercial deposit located in Rio Branco – AC and later characterized through particle size tests, X-Ray Diffraction, X-Ray Dispersion Spectroscopy and Tropical Compressed Miniature essay. The dispersion of nanotubes in solution was carried […]
Pull-Out Response Of A Geogrid Buried In Recycled Sands
Recycled construction and demolition waste (RCDW) has demonstrated geotechnical properties that encourage it to be used in reinforced soil structures (RSS) with geosynthetics. However, the interaction between RCDW and reinforcements needs to be better understood, given its importance for design. This paper presents a qualitative study on the interaction between geogrid and recycled sands by […]
Parameters Controlling The Expansive Behavior Of Bentonite-Kaolin Mixtures Stabilized With Alkali-Activated Waste
Expansive soils can cause large-scale damage to the infrastructure. Soil stabilization with Portland cement and lime has been widely utilized as a solution to this problem. However, these stabilizers are non-renewable and energy-intensive. Alkali-activated binders are alternatives with lower carbon dioxide emissions. This research evaluated an expansive soil stabilization with an alkali-activated binder produced from […]
Influence Of Suction On The Parameters Of The Marchetti Dilatometer Test On A Compacted Residual Soil
This study had the objective to evaluate the application of the Marchetti Dilatometer Test (DMT) on compacted residual soil, analyzing the influence of suction on the parameters obtained. For this, a sample of residual diabase soil was collected and compacted in the laboratory at its optimum moisture content. Granular matrix suction sensors (GMS) were installed […]
Numerical Evaluation Of The Influence Of Compaction And Soil Strength Parameters On Grsw
This paper presents a numerical evaluation, using PLAXIS 2D finite element software, of the effects of varying the distance of the heavy compaction from the face in a geosynthetic reinforced soil wall (GRSW). The main effects studied were the tensions in the reinforcements and the horizontal deformations of the face, including the influence of the […]
Compressive And Tensile Strength Of Aeolian Sand Stabilized With Porcelain Polishing Waste And Hydrated Lime
The improvement of sandy soils by incorporating new stabilizing agents in a physical and/or chemical process has become the subject of many studies in recent decades. In addition, the use of industrial wastes in this process can bring significant benefits to the environment and savings in natural resources. This work aims to evaluate the implications […]
Assessment Of Bauxite Residue Stabilized With Lime And Graphene Oxide As A Geomaterial For Road Applications
Negative traits of bauxite residue (BR) include low shear strength, inconsistent compaction characteristics and dispersion, render it unsuited geomaterial for engineering applications. The present study aims at stabilizing BR with the combination of lime (L) and graphene oxide (GO) in suitable proportions and investigating their impact on improvement in engineering properties (viz., density, unconfined compressive […]
