Welcome to the British Geotechnical Association (BGA). We are the principal association for geotechnical engineers in the United Kingdom. We also perform the role of the Ground Board for the Institution of Civil Engineers, as well as being the UK member of the International Society for Soil Mechanics & Geotechnical Engineering (ISSMGE) and the International Society for Rock Mechanics and Rock Engineering (ISRM).
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.
Mike Winter will present a wide-ranging view of hazard and risk assessment of debris flow events.
