Overview geotechnical model tests on dike safety at Deltares

Three on-going dike safety studies (on: macro stability, piping and flow slides) in the Netherlands make use of geotechnical physical models. A short outline of these projects is presented; the physical models chosen are described and discussed. The three studies use different physical models, depending on the research questions at the beginning...

Field tests for operational shear strength assessment in peat at Uitdam, The Netherlands

Stability assessment of existing dikes build on soft soil generates questions on the available stability calculation techniques and material models. Especially peat behaviour is not easily captured by standard design methods. This has led to disapproval, based on calculations, of dikes that have been in operation for several hundreds of years....
