WHY
A.S. Keverling Buisman becomes professor at TU Delft
In order to be able to build safely with and/or on top of soil, its geotechnical properties need to be measured. Buismans Dutch cell test apparatus is the predecessor of current devices used for these measurements.
HOW
Landslide in Weesp
A soil sample is surrounded by water in a closed cell. A vertical load generates a vertical deformation and increase in the cell pressure. These parameters indicate important soil properties such as the maximum allowable load. 15
