CRUX Graduation Assignment - Creep S-Clay1S model: modelling of creep near slopes

CRUX is a leading independent consulting firm in the field of geotechnical engineering, geohydrology and environmental remediation.

Through our intensive cooperation with our sister companies BouwRisk (monitoring) and CEMS (engineering microservice), we are able to provide innovative, (geo)technical design solutions for all subsurface issues.

Modelling creep in, under and adjacent to a soil body is "common practice" in geotechnical projects. A common model in PLAXIS is Soft Soil Creep (SSC). However, the use of the isotropic model SSC has a number of disadvantages, especially as the steepness of the slope increases.

There is now an alternative user defined soil model to the SSC model: the Creep SCLAY1S model. Although little practical experience exists with this model, it seems more suitable for modelling creep-related deformations at steep slopes. 

A plan of action for a graduation thesis was prepared in collaboration with a TU Delft thesis committee consisting of Ronald Brinkgreven, Cor Zwanenbrug and Arny Lengkeek. The main themes for this research are:

  1. A parametric study;
  2. Sensitivity study on overconsolidation
  3. Modelling of creep in and underneath a dike in Plaxis
