...U. R. Albino; F. H. M. Portelinha; M. M. Futai This paper presents a numerical method for considering soil-atmosphere interaction applied to infiltration into an unsaturated geosynthetic reinforced soil wall and its effect on wall stability. A hypothetical nonwoven geotextile reinforced soil wall...

...R. Plácido; F. H. M. Portelinha; M. M. Futai Laboratory and field investigation of time-dependent behavior of geotextiles reinforcing a fine-grained soil are evaluated herein. The field assessment consisted of analyses of two instrumented sections of a geotextile reinforced soil wall with identical...

...F.H.M. Portelinha; J.G. Zornberg; V. Pimentel ABSTRACT: This paper presents an evaluation of the performance of two instrumented sections of a geosynthetic-reinforced soil wall, 5.6 m high, constructed using a lateritic fine-grained soil. Two sections with identical layout of a nonwoven and a woven...

... were lost. In addition to the damage to concrete structures, seawalls were seriously damaged, probably as a result of scouring. On the other hand, some reinforced soil walls were barely damaged, although they were inundated by the tsunami. This paper briefly reviews the reinforced soil walls in Japan...

...F.H.M. Portelinha; B.S. Bueno; J.G. Zornberg ABSTRACT: The first geosynthetic retaining wall in Brazil was constructed in 1984 as an instrumented 10 m high geotextile-reinforced soil wall with a poorly draining backfill. This structure has been showing excellent performance throughout its service...

... was minimised by applying lubricant to the inner surface of the test box. The wall-facing column was created by stacking wooden blocks 3 cm high, 5 cm wide and 48 cm long, with a pin-type connection at the two ends. Geosynthetics Reinforced soil wall Tiered walls Reduced-scale models Similitude...

... reinforced soil mass, or modelled as different materials. The concept proposed by de Buhan et al. (1989) may be used for homogenisation. Finite element studies of reinforced soil walls as homogenised reinforced soil masses were performed by Romstad et al. (1976), Singh and Basudhar (1993...

...J. Izawa; H. Ito; T. Saito; M. Ueno; J. Kuwano ABSTRACT: The combined use of a geogrid-reinforced soil wall with a fibre-mixed soil-cement wall (GRSW-FSC) has recently been developed, and its application has grown rapidly. The results of previous centrifuge shaking-table tests have clearly shown...

... of reinforced soil walls under static and seismic loads. The reliability indices evaluated by the three methods of reliability analyses were compared for both the internal and external stability of the wall. Based on the results, it is concluded that the friction angle (ϕ) is the most sensitive random variable...

... sets the technical standard in Japan for the design and construction of earthworks involving geosynthetic reinforced embankments and walls. This paper describes the design of reinforced embankments using clayey soil fills with high water contents and the design of reinforced soil walls. A construction...
