Research by Joseph Birnie, an Engineer at CGL’s London office, has been shared at the Numerical Analysis in Geotechnics seminar in Ho Chi Minh City, Vietnam by JaeSeok Yang of MIDAS.
The research by Joseph was the basis of his MSc thesis while he was at the University of Birmingham where he graduated last year. He used Finite Element (FE) analysis to predict ground movements during excavation and the effects on adjacent structures. Working with Crossrail and Mott MacDonald, Joseph was able to compare his predictions against real data generated by excavation of the Moorgate Shaft for the Crossrail project in London. The comparison showed actual movements to be close to predictions, validating the approach used and the ground model that he developed.
The results and conclusions were used by the geotechnics team at MIDAS, provider of the numerical analysis system that Joseph used, in a presentation to delegates at the NAG2018 International Seminar organised by universities in Vietnam and Taiwan.
