Om
Forskningsemner:
- Ulike prosjekter vedrørende jordmodellering. Dette inkluderer:
- Modellering og forståelse av kryp i bløt leire og andre aspekter ved jords oppførsel.
- Utvikling og implementering av en rekke jordmodeller, inkludert NGI-ADP-modellen som nå er en del av et kommersielt endelig element-program (www.plaxis.nl).
- Progressiv brudd i sensitiv leire. Dette inkluderer:
- Arbeide med implementering av en regulariseringsteknikk for modellering av sprøbruddmaterialoppførsel i endelig element-beregninger.
- Tilbakeberegninger av skred som involverer kvikkleire.
