Retaining wall with reinforced backfill – a case study

Evaluation of the effect of compaction on the behavior of geosynthetic-reinforced soil walls

“…In recent decades, several experimental and numerical investigations have been carried out to determine the effective parameters in GRS walls (Fishman et al, 1993;Palmeira and Gomes, 1996;Ho and Rowe, 1996;Tatsuoka et al, 1997a,b;Rowe and Ho, 1998;Garg, 1998;Ling et al, 2000;Rowe and Skinner, 2001;Koerner and Soong, 2001;Yoo, 2004;Kazimierowicz-Frankowska, 2005;Bathurst et al, 2005;Benjamim et al, 2007;Hatami and Witthoeft, 2008;Yoo and Kim, 2008;Liu and Won, 2009;Yang et al, 2009;Ahmadabadi and Ghanbari, 2009;Liu, 2012). However, despite these extensive investigations, the effect of compaction has been rarely considered.…”

Analysis and Design of Retaining Wall having Reinforced Cohesive Frictional Backfill

“…Garg and Saran (1997) discussed a concept of economical placement of the unattached reinforcement in the backfill for vertical walls and also provided non-dimensional design charts. Garg (1998), Mittal et al (2001 and Garg et al (2002) have tried to establish the validity of the ANALYSIS AND DESIGN OF RETAINING WALL analytical approach developed by Garg (1988) and reported by Saran et al (1992), through prototype rigid walls, retaining geogrid reinforced cohesionless earth fill.…”

Lower bound analysis of modified pseudo‐dynamic lateral earth pressures for retaining wall‐backfill system with depth‐varying damping using FEM‐Second order cone programming

“…The flowchart of step-by-step computational procedure followed in the current study the literature. [90][91][92][93][94][95] In this regard, Garg 90 presented a case study on the construction of an 11-m reinforced retaining wall in the Himalaya regions backfilled with cohesionless soil having internal friction angle of about 35 • . In separate studies, Bathurst 95 and Latha and Krishna 96 constructed a 0.8 and a 4-m reinforced retaining wall, respectively, backfilled with sand having internal friction angle equal to about 35 • to 38 • .…”

“…Allen et al 92 have conducted a comprehensive experimental study on a full-scale laboratory reinforced retaining wall of about 6 m height with sand backfill having an internal friction angle of 40 • . In addition, Garg 91 and Bathurst et al 94 gathered a collection of 25 case histories on the reinforced walls with heights varying from 3 to 12.6 m backfilled with sand having an internal friction angle of about 40 • . As the parametric survey conducted in the course of this study covers a wide range of variables, the performance of the aforementioned F I G U R E 4 Spectral lateral earth pressure coefficients for (a) active and (b) passive limit states ( ℎ ∕(1 − ) = 0.2) constructed walls against the pseudo-dynamic loading could be effectively evaluated using the results of the specific analyses in the current study.…”
