Slipped Disk
Researchers at the University of Sheffield have developed a revolutionary new computational technique for geotechnical stability analysis – discontinuity layout optimisation (DLO).
Until now geotechnical engineers have had to rely either on hand calculation methods, a suite of single method programs or on more complicated finite element packages. But with DLO, any type of stability problem involving slopes, foundations and retaining walls can be solved using a single software program. DLO uses modern optimisation technology to directly identify the layout of slip-lines (or discontinuities) that define a critical failure mechanism.
University of Sheffield spin-out company LimitState launched the first DLO-based product, LimitState:GEO earlier this year.
LimitState:GEO and the DLO technology was recently the subject of an article in Ground Engineering, the leading international monthly magazine for Ground Engineers. Covering the history of DLO and its application in LimitState:GEO, the article describes some of the many benefits that this new approach to geotechnical ultimate limit state analysis can bring to the practising engineer.
