Determination of Bearing Strength Characteristics of Fine and Coarse Cohesive Soils from its Index Properties
Abstract: The variation in geology, cost and complexity in the preparation and testing for strength characteristics of soils from location to location has challenged geotechnical engineers to make optimum use of empirical formulas to predict bearing strength characteristics of soils. One major One major One major One major One major One major problem associated with bearing capacity of soil includes the different engineering properties associated with different geologic formations which have …

First experimental results on “clay and bentonite” mixtures for the waterproofing of a landfill in Northwestern Piedmont Region (NW Italy)
Abstract: We report on experimental results conducted on “clay and bentonite” mixtures for the waterproofing of a tank landfill located in Northwestern Piedmont Region (NW Italy).The geotechnical experimental tests on “clay and bentonite” mixtures were conducted in the laboratory first, with the aim of finding the optimum percentage of granular bentonite to be added to the clay and then, they were carried out in situ, in the tank, on the layer …

Shallow Seismic Refraction Investigation for Site Classification and Geotechnical Engineering Applications
Abstract: The survey was carried to determine the Site Class of the study area and also estimate some geotechnical parameters of potential construction sites within the study area. The survey was conducted on the University of Mines and Technology (UMaT) campus, using Geometrics ES 3000, A 12-Channel seismograph developed by Geometric Inc. The results from the study show that the subsurface of the study area is made up of four layers. …

Laboratory permeability and single ring infiltration tests for the testing of waterproofing barriers of landfill tanks.
Abstract: Hydraulic conductivity is a fundamental hydrogeological parameter for the testing of waterproofing barriers of landfill tanks. These barriers are aimed at guaranteeing the isolation of the waste and preventing the infiltration of the percolate in the subsoil.Geotechnical features of mineral barriers must be preliminarily established through geotechnical laboratory tests in order to verify their suitability for their application.The main mineral barriers correspond to the bottom waterproofing of the landfill tanks …

SYMMETRY AND ASYMMETRY MODEL FOR THERMAL CONDUCTIVITY IN POROUS MEDIA
Abstract: This paper focuses on determining thermal conductivity in porous media using symmetry and asymmetry models. Since porous media are not uniform and homogeneous in most of the cases, anisotropy must be taken into account, what derives in the application of an asymmetry model as thermal gradients are not equal in all directions. The paper demonstrates that, under certain conditions, isotropic conditions, therefore, symmetry model can be applied to non-homogeneous or …
