Modern approach to numerical modelling of anchored protective structures
radu je opisan suvremeni pristup numeričkom modeliranju sidrenih zaštitnih konstrukcija s osvrtom na iskustva u primjeni računalnog programa Plaxis 2D i modela tla s izotropnim očvršćivanjem. Objašnjena su osnovna obilježja u ponašanju tla u dreniranim i nedreniranim uvjetima za naprezanja koja se pojavljuju pri iskopu građevne jame. Prikazan je primjer simulacije sidrene zaštitne konstrukcije i dane su smjernice za strategiju odabira parametara materijala HSs modela tla.modern approach to numerical modelling of anchored protective structures is presented in the paper, and an overview is given of experience gained in the use of the Plaxis 2D computer program, and soil model with isotropic strengthening. Basic properties of soil in drained and undrained conditions, due to stress occurring during foundation pit excavation, are explained. An example involving simulation of an anchored protective structure is presented, and guidelines for the selection of soil materials for the HSs soil model are given
