Role of Composition, Structure and Physico-Chemical Environment on Stabilisation of Kuttanad Soil
(2018-04-12)
Soft soil deposits of coastal regions and lowland areas pose many geotechnical problems but it is indispensable to utilize these grounds to meet the growing demand for infrastructure with ever increasing urbanization and ...
Influence of Permeation of Synthetic Groundwater Solutions on the Hydro-Mechanical Proerties of Barmer Bentonite
(2018-04-11)
The deep geological repository concept is based on “engineered barriers systems (EBS)” that are constructed in the repository and “natural barriers” provided by the surrounding geological environment. The EBS comprises of ...
Shape Characterization of Granular Particles using Image Based Techniques
(2018-05-22)
Granular soils with different sizes and shapes are often used in many civil engineering structures. In different contexts, several researchers have emphasized that shape of particles play a pivotal role in influencing ...
Studies on Propagating and Non-Propagating Cracks in Concrete Under Fatigue Loading in the Short Crack Regime
(2018-05-01)
Structural concrete is the most widely used material in the construction of bridges, pave-ments, runways, dams and other infrastructures which are subjected to uctuating loads during its service period. Concrete contains ...
Smooth Finite Element Methods with Polynomial Reproducing Shape Functions
(2018-04-03)
A couple of discretization schemes, based on an FE-like tessellation of the domain and polynomial reproducing, globally smooth shape functions, are considered and numerically explored to a limited extent. The first one ...
Modeling Salinity Impact on Ground Water Irrigated Turmeric Crop
(2018-04-18)
Soils in irrigated fields are impacted by irrigation water quality. Salts in the irrigation water may accumulate in the soil depending on amount of leaching, the quality of water and type of ions present. Salinity is an ...
Stochastic Modelling of Flexible Pavement Performance
(2017-11-16)
Stochastic analysis provides a rationale for the treatment of uncertainties, founded on the principles of probability theory and statistics, and is concerned with a quantifiable measure of the confidence or the reliability ...
Finite Element Limit Analysis for Solving Different Axisymmetric Stability Problems in Geomechanics : Formulations and Solutions
(2017-11-15)
Limit analysis is a very powerful tool to find accurate solutions of several geotechnical stability problems. This analysis is based on the theory of the plasticity and it provides two limiting solutions within lower and ...
A Hydroclimatological Change Detection and Attribution Study over India using CMIP5 Models
(2017-11-14)
As a result of increase in global average surface temperature, abnormalities in different hydroclimatic components such as evapotranspiration, stream flow and precipitation have been experienced. So investigation has to ...
Upper Bound Finite Element Limit Analysis for Problems of Reinforced Earth, Unsupported Tunnels and a Group of Anchors
(2017-11-27)
This thesis presents the implementation of the upper bound limit analysis in combination with finite elements and linear optimization for solving different stability problems in geomechanics under plane strain conditions. ...
