CRUX Graduation Assignment - Stability of a low embankment in the proximity of a waterway
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 issues in the subsurface. One such issue concerns bearing capacity for low embankments on weak soils.
It is commonly considered that the first stage of building the embankment, for example the first 1.5 meter of sand for the work floor of a drainage machine, can be applied to the subsurface without problems. In recent projects, CRUX has experienced that these low embankments on very weak soils and in the presence of a waterway can still fail, contrary to expectations. This collapse does not follow from the usual design calculations with DGeoStability and the failure mechanism looks more like squeezing.
The assignment consists of using Plaxis to analyze the failure that can occur and come to a design approach such that based on the strength of the subsoil and the distance between the waterway and the embankment, a good design can be made for the installation of the first stage.
