The fictitious force method for efficient calculation of vibration from a tunnel embedded in a multi-layered half-space
(
Elsevier
, 2014 , Article)
This paper presents an extension of the Pipe-in-Pipe (PiP) model for calculating vibrations from underground railways that allows for the incorporation of a multi-layered half-space geometry. The model is based on the ...
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 ...
Quantifying morphology of sands using 3D imaging
(
American Society of Civil Engineers (ASCE)
, 2015 , Article)
Particle morphology plays a significant role in influencing engineering behavior of granular materials. Surface texture, roundness, and sphericity represent distinct multiscale measures needed to fully describe particle ...
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 ...
Real-Time Dynamic Transit Signal Priority Optimization for Coordinated Traffic Networks Using Genetic Algorithms and Artificial Neural Networks
(
Taylor and Francis Inc.
, 2015 , Article)
Transit signal priority (TSP) has gained popularity in providing public transportation buses with preferential treatment at signalized intersections. Many studies have addressed its implementation in prompting enhanced ...
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 ...
