Reforço de solos moles em Deep soil mixing para fundação de aterro

Abstract

In the present work an embankment on soft soil is analyzed with commercial finite element software (Plaxis® ) in order to compare the solution implemented on site (with drains and preloading) with a soil improvement solution in Deep Soil Mixing (DSM). Several alternative solutions in DSM were studied changing the column spacing, the curing time, as well as the inclusion of a load transfer platform. For each case the settlements were analyzed and compared to evaluate if the necessary requirements in terms of limit values were satisfied. Finally, a cost-benefit analysis was performed focused on the execution time and cost of each solution.
