BGA ECG Desk Study to Design CPD Course 1: Desk Study

To be hosted by Groundsure, this session will run through the importance of completing a detailed desk based review of site conditions prior to undertaking works on site.

BGA ECG North - Geotechnical Early Careers Seminar with University of Nottingham

BTSYM-BGA ECG Workshop : Ground Movement Assessments Using XDisp/PDisp

This workshop aims to provide useful insights in the use of Oasys XDisp and PDisp to carry out ground movement assessments (GMAs). Target audience is early career tunnelling engineers and geotechnical engineers.

BGA ECG - Preparing for ICE chartered professional review

The BGA Early Career Group’s flagship event returns for 2022. Presented annually by two ICE Reviewers, ‘Preparing for ICE Chartered Professional Review’ provides practical guidance to engineers seeking chartership with the ICE.

BGA ECG / NAFEMS COGAN technical webinar: Strength reduction technique for slopes with finite element methods

Speaker: Professor H. F. Schweiger (TU Graz)

Summary: Although limit equilibrium analyses currently dominate in practical geotechnical engineering to obtain factors of safety of natural and cut slopes, the finite element method is increasingly being used to calculate ultimate limit states and consequently factors of safety, usually by means of the so-called “strength reduction” technique. In many cases results obtained from the strength reduction approach are comparable to the those obtained with limit equilibrium methods, but in some cases significant differences are observed. By comparison with rigorous limit analyses, it is at first demonstrated that the strength reduction method is a reliable method for analysing failure of slopes. Secondly, it is shown that finite element analyses are superior to limit equilibrium analyses in assessing ultimate limit state conditions. Finally some guidelines for performing strength reduction analyses are given.

BGA ECG Academic Talk: The Effects of Weathering on the Chalk Unsaturated Zone

The Chalk aquifer is a strategic resource for the water supply across ~21,500 km2 of the UK and is increasingly under pressure from changes in demand due to climate change.

Tony will discuss how his work in the field and lab aim to further understanding and characterisation of development of weathering in the chalk unsaturated zone (CUZ). Evaluating permeability and porosity in respect to flow regime, and geomechanical changes.
Tony is currently a PhD researcher at Imperial College London within the Geotechnics Cluster.
