Effects of air permeability and perimeter area on air losses in compressed air tunnelling
Presentation / Conference
Ahangar Asr, A., & Javadi, A. Effects of air permeability and perimeter area on air losses in compressed air tunnelling. Presented at 23rd UK Conference of the Association for Computational Mechanics in Engineering, Swansea, UK

Field measurement data obtained from a tunnel in Munich was used to develop a model to predict air losses in the process of compressed air tunnelling. In the implemented case study, compressed air was used to control the groundwater followed by placi...

Stability analysis of geometrically non-homogeneous stratified slopes
Presentation / Conference
Sauffisseau, R., & Ahangar Asr, A. Stability analysis of geometrically non-homogeneous stratified slopes. Presented at 25th UKACM Conference on Computational Mechanics, University of Birmingham, Birmingham, United Kingdom

Due to ongoing construction of cities and development of new buildings and infrastructures, many natural slopes in and around urban areas are often subjected to cuts. These excavations result in dramatic changes in the geometry of slope faces mostly... Read More about Stability analysis of geometrically non-homogeneous stratified slopes.

Numerical investigation into the effect of various surcharge loadings on propped wall excavations and embankments
Presentation / Conference
Ogunyemi, O., & Ahangar Asr, A. Numerical investigation into the effect of various surcharge loadings on propped wall excavations and embankments. Presented at UK Association for Computational Mechanics 2020, Loughborough University

Several guidance and formulation have been developed in the literature to account for the analysis of external surcharges adjacent to a propped excavation but less attention has been paid to the presence of sloping ground or embankments. However, CIR... Read More about Numerical investigation into the effect of various surcharge loadings on propped wall excavations and embankments.

Relationship between shallow foundation shape and contact area, and the settlement in granular soils
Presentation / Conference
Starkey, T., & Ahangar Asr, A. Relationship between shallow foundation shape and contact area, and the settlement in granular soils. Presented at UK Association for Computational Mechanics (UKACM) Conference 2021, Loughborough University, UK

The aim of this investigation is to discover the effects of foundation shape and contact area on foundation settlement. There is little research at the current time which relates the increase in size or scale effects to the settlement, with current r...

The effect of cut-off wall angle on seepage and uplift pressure under dams
Presentation / Conference
dams. Presented at UK Association for Computational Mechanics (UKACM) Conference 2021, Loughborough University, UK

Seepage under dams can result in high uplift pressure experienced usually under the downstream of the dam which may lead to instability and potentially the failure of the dam. Cut-off walls are the primary solution to minimize the effects caused by t... Read More about The effect of cut-off wall angle on seepage and uplift pressure under dams.
