Dam Stability Assessment – Limit Equilibrium Analysis (LEA) or Finite Difference Analysis (FDA)?

By Red Earth Engineering In Geotechnical Engineering, Tailings and Water Dams No comments

Limit equilibrium analysis (LEA) for slope stability assessment became popular since Bishop’s method of slices was first introduced in 1955, followed by a number of variations. Although advanced numerical methods such as finite element analysis (FEA) or finite difference analysis (FDA) have been actively developed since personal computers became available, engineers keep holding on to…

REE presenting at ANCOLD 2016

By Red Earth Engineering In Geotechnical Engineering, News, Tailings and Water Dams No comments

Robert Harrington, a senior engineer with REE, has had his paper abstract ‘assessing blast impacts on embankment dams’, accepted by ANCOLD for oral presentation. REE have recently been involved in numerous mining projects where blasting activities are occurring adjacent to existing active tailings storage facilities. Rob has undertaken a thorough literature review and provides recommendations…
