Resumo: | The present study has the objective of analyze numerically the behavior of two instrumented experimental landfills (landfill test A and landfill test B), located in the area that composes the Palms Recreio Condominium Residential. The landfill test A was built on a layer of soft clay of 8.0 m thick, where drains were installed for acceleration of settlements. In the area of the landfill test B, in addition to the installation drains, the squeezing of compressible soil through the CPR Grouting technique was carried out, in order to significantly reduce the expected settlements. In each test landfills have been installed 3 plates for measuring the vertical displacement, 5 vertical magnetic spiders, 1 profilometer for monitoring the vertical displacements, 2 piezometers to control porepressure and 1 inclinometer for monitoring the horizontal displacements To reproduce the behavior of experimental landfills, the Plaxis program of finite elements was adopted. Initially, the calibration of the model was carried out, comparing the numerical predictions obtained for the landfill test A (without CPR Grouting) with the data provided by field instrumentation. Subsequently, the prediction of the behavior of the landfill test B (with CPR Grouting) was carried out, looking for representative deformability parameters of the stiffened soil. The main conclusions are the increase in soil rigidity after stiffening with the CPR Grouting technique, leading to significant reductions of the displacements. The deformability modulus (E) of the soil with CPR Grouting was 12 times higher than that of the soft soil without CPR Grouting. In addition, the stiffening leads to a homogenization of the compressible soil layer. |

O aterro teste A foi construído sobre uma camada de argila mole de 8,0 m de espessura, onde foram instalados geodrenos para a aceleração dos recalques. Na área do aterro teste B, além da instalação de geodrenos, foi realizado o enrijecimento do solo compressível através da técnica CPR Grouting, de forma a minorar significativamente os recalques previstos. Em cada um dos aterros testes foram instalados 3 placas de recalque, 5 aranhas magnéticas verticais, e 1 perfilômetro, para monitoramento dos recalques, 2 piezômetros, para controle das poropressões, e 1 inclinômetro, para acompanhamento dos deslocamentos horizontais. Para a reprodução do comportamento dos aterros experimentais, foi adotado o programa Plaxis, de elementos finitos. Inicialmente, procedeu-se à calibração do modelo, confrontando-se as previsões numéricas obtidas para o aterro teste A (sem CPR Grouting) com os dados fornecidos pela instrumentação de campo. Posteriormente, foi realizada a previsão do comportamento do aterro teste B (com CPR Grouting), buscando-se parâmetros de deformabilidade representativos do solo enrijecido. Como principais conclusões, destaca-se o aumento da rigidez do solo após o enrijecimento com a técnica CPR Grouting, conduzindo a reduções significativas de recalque. O módulo de deformabilidade (E) do solo com CPR Grouting mostrou-se 12 vezes superior ao do solo mole sem CPR Grouting. Adicionalmente, o enrijecimento conduz a uma homogeneização da camada de solo compressível.Submitted by Boris Flegr (boris@uerj.br) on 2021-01-06T19:03:19Z No. of bitstreams: 1 Leonardo Jose Nieto Cunha Gondariz.pdf: 11133616 bytes, checksum: a8d1f6511ac74d0678f83670aab2d8e0 (MD5)Made available in DSpace on 2021-01-06T19:03:19Z (GMT).
