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…
