1-g physical modelling of shallow foundation treated with polypropylene-reinforced soil-cement columns in liquefiable soil

The fibre-reinforced soil-cement columns are used as remediation measure against earthquake induced soil-liquefaction associated large settlements in liquefiable loose surface layer of sand. This sand was overlying on the non-liquefiable dense bottom 1-g physical modelling shallow foundation carried out using shaking table. There were four models constructed for testing and two types improvements such adjacent beneath structure. First model without improvement, three with provision polypropylene-reinforced columns. In first treated installed wooden fixity plate to structure, second improved improvement upon soil-cemented provided third results obtained case untreated concludes that penetration structure inside soil settlement both up unacceptable limits. unacceptable. achieved up-to acceptable most successful type liquefaction-induced which values negligible.
