Abstract

The fundamental causes of levee failure produced by piping and erosion were studied and the safety of river levees during floods evaluated in terms of soil mechanics. Elastic-plastic deformation of a levee owing to changes in the water level in a river was calculated by finite element analysis. The extent of the plastic region of levee failure was determined and the relation of displacement to the safety factor for the levee explained. The critical hydraulic gradient and the process of progressive failure were obtained from one- and two-dimensional model experiments for piping and erosion. Problems inherent in and preventive measures against levee failure are discussed.
