An integrated ANP and er condition assessment model for sewer pipelines
(
International Society for Trenchless Technology
, 2015 , Conference Paper)
As sewer networks age, the need for their maintenance arises. Simultaneously, inadequate rehabilitation of sewer pipelines might cause catastrophic failures. Thus, municipalities worldwide must have a detailed knowledge ...
A mixed space-time and wavenumber domain model for predicting ground vibration from railway tracks
(
National Technical University of Athens
, 2015 , Conference Paper)
In this paper, a mixed model for studying ground vibration generated from surface railway tracks is presented. A ballasted track with nonlinear resilient components is modelled in the time domain using the Finite Element ...
Experimental validation of a numerical model for the ground vibration from trains in tunnels
(
DC/ConfOrg
, 2015 , Conference Paper)
Ground vibration and ground-borne noise from trains in tunnels are attracting increasing attention from researchers and engineers. They are important environmental issues related with the operation of underground networks ...
Modelling the dynamic pile-soil-pile interaction in a multi-layered half-space
(
DC/ConfOrg
, 2015 , Conference Paper)
Within the context of railway ground-borne vibration, the dynamic pile-soil-pile interaction remains an area that has not been sufficiently investigated. Whilst a number of researchers have scrutinised the vibration response ...
Effect of rail unevenness correlation on the prediction of ground-borne vibration from railways
(
DC/ConfOrg
, 2015 , Conference Paper)
This paper presents the influence of rail unevenness correlation on the predicted track and ground vibration. The study is based on an integrated railway model in the wavenumber-frequency domain with varying complexity ...
Status quo and critical review of PPV safe limits for subsurface construction blasting close to low-rise buildings
(
Taylor and Francis - Balkema
, 2013 , Conference Paper)
Subsurface construction blasting may result sever man-made ground vibrations.Waves generated due to detonating a charge in a solid medium like rock generate particle movement and travel at different wave velocities. As ...
A framework for construction workspace management: A serious game engine approach
(
2012 ASCE International Conference on Computing in Civil Engineering
, 2012 , Conference Paper)
Construction workspace is regarded as one of the main constraints on construction sites. Construction workspaces are generally difficult to proactively plan and manage due to the dynamic nature of a site where workspace ...
Fatigue characterisation of full-scale pavements using viscoelastic continuum damage approach for qatar
(
CRC Press/Balkema
, 2015 , Conference Paper)
The population and economy in Qatar have been expanding significantly in the past six years. Accordingly, Qatar is encountering huge development in infrastructure. The existing mix design methods have been developed in the ...
Characterisation of fatigue resistance of alternative pavement design for the state of Qatar
(
Taylor and Francis - Balkema
, 2014 , Conference Paper)
Asphalt mixtures have been designed in the past in the State of Qatar to safeguard against permanent deformation associated with high temperatures. These mixtures are typically designed to have low content of unmodified ...
Assessment of linear and nonlinear viscoelastic responses of warm-mix asphalt binders
(
CRC Press/Balkema
, 2015 , Conference Paper)
Warm-Mix Asphalt (WMA) technology is widely used in the paving industry due to its impact on reduction of asphalt mixing and compaction temperatures. Characterisation of WMA in the past had focused on evaluating the linear ...
