Modelling of plastic culvert and road embankment interaction in 3D
A series of 3D Finite Element simulations was performed to investigate the effect of different factors influencing the distortions undergone by a plastic culvert tube while subject to external loading from a heavy truck. ...
Comparison of community managed projects and conventional approaches in rural water supply of Ethiopia
This study aimed to compare Community Managed Projects (CMP) approach with the conventional approaches (Non-CMP) in the case of Ethiopia. The data collection methods include a household survey (n=1806), community representative ...
Systemic inequalities in indoor air pollution exposure in London, UK
Deprived communities in many cities are exposed to higher levels of outdoor air pollution, and there is increasing evidence of similar disparities for indoor air pollution exposure. There is a need to understand the drivers ...
Spatio-temporal Analysis of Open Waste Dumping Sites Using Google Earth : A Case Study of Kharagpur City, India
Google Earth provides high-resolution satellite images over a long period of historical time period which can be used to study land use/land cover (LULC) changes in any area over an extended period of time. In this study, ...
Air Pollution, housing and respirfatory tract Infections in Children : NatIonal birth Cohort study (PICNIC): study protocol
INTRODUCTION: Respiratory tract infections (RTIs) are the most common reason for hospital admission among children <5 years in the UK. The relative contribution of ambient air pollution exposure and adverse housing conditions ...
Uncertainties in modelling undrained shear strength of clays using Critical State Soil Mechanics and SHANSEP
The determination of the undrained shear strength of clays relies upon the goodness of the available in-situ and laboratory tests. Often, limited soil investigation data is available, or the collected data may suffer of ...
Small strain stiffness within logarithmic contractancy model for structured anisotropic clay
Stiffness of soils in the small strain region is high and it decays nonlinearly with increasing shear strains or with mobilization of shear stresses. However, the commonly used critical state based constitutive models use ...
Cracking of the End Diaphragm of a Post-tensioned Beam Bridge
In concrete beam bridges, the end diaphragm at the end of the bridge is a common structural component that connects the main beams and transfers the beam loads to the bridge bearings. In integral bridges the end diaphragm ...
Commercialising reclaimed materials in earthworks – guidelines for productization and the process of appending these materials in the Finnish national code of practice
(Icelandic Geotechnical Society, 2016)
To decrease the use of non-renewable natural resources as well as environmental effects of earth-works, natural aggregate materials can be replaced with recycled materials acquired from surplus soil, industrial by-products ...
Shear wave velocity as a tool for characterising undrained shear strength of Nordic clays
There has been increasing recent use of shear wave velocity (Vs) measurements in geotechnical engineering practice. This has been driven by advances in cost effective and efficient methods of determination of Vs. Traditionally ...
