“…1. This is consistent with the model reinforcement test results as reported by Pinto and Cousens [40]. Hence, an attempt has been made in this present study by considering a different way of approach for an idealized tensile stress-strain behavior of the model reinforcement material as presented in Fig.…”

It is reported in the literature that the load-carrying capacity of the reinforced sand bed increases with increasing the footing settlement. However, the nature of settlement plays a critical role in shallow foundation designs due to the conditional allowable settlement of the footings. In this present study, laboratory model tests have been performed on a model jute geotextile reinforced sand bed under 1g condition. The associated scaling laws are adopted for the geometrical parameters of the model footing and reinforcements as proposed in the literature. On the other hand, a new approach has been developed for the model reinforcements for scaling down of geosynthetic materials under 1g condition to simulate the condition of geosynthetic reinforcement layers as in the eld or Ng conditions. The test results revealed that based on the scaling factors the model footing can be allowed to settle according to the criteria of footing settlement and allowable reinforcement tensile strains. Finally, the suitable guidelines have also been developed as per the safety considerations in order to understand the effect of reinforcement layers on the improvement of soil bearing capacity ratio (BCR) up to a certain settlement ratio (s/D) of the footing.

“…To simulate the model test results as carried out in the laboratory under 1g and Ng conditions, the scaling laws should also be applied for the size of soil particles with a scaling factor of N [35,40]. However, several researchers have different views with respect to considerations of scaling of the size of soil particles.…”

-In this paper the behavior of reinforced earth walls with rigid and flexible faces under strip footing load was studied by numerical analysis. In one numerical model the strip footing load was free to have horizontal and vertical movements and in another the horizontal movement of the strip footing load was restricted. By considering these two different models, the results of 2D and 3D numerical analysis (Plaxis) were compared with the full scale test results about the horizontal earth pressures, lateral wall deflections and consequently maximum tensile force on reinforcement layers. For modeling the compaction loads in each layer two equal distributed loads were considered in the top and bottom of each soil layer and also the influence of sidewall friction was studied in a 3D numerical analysis. Results showed that there is good agreement between 3D numerical analysis and full scale test results by considering the horizontal restriction for the strip footing load.

“…In order to investigate the characteristics of behavior and failure mechanisms of reinforced retaining walls, model tests and numerical analyses were carried out by changing the length and spacing of reinforcement, surcharge load, and backfill properties studied by Wong, Pinto, Leshchinsky, Ghionna, Yoo, Liu, Stuedlein, and Suliman [1][2][3][4][5][6][7][8]. The safety of construction structures according to vehicle collision was verified with vehicle crash tests and numerical collision analyses by Wu, Borovinšek, Chung, Itoh, Tay, and Kim [9][10][11][12][13][14].…”

Accidents involving vehicles crashing into reinforced retaining walls are increasing because of the increased construction of reinforced retaining walls on roads. Unlike a normal retaining wall, a reinforced retaining wall is not one united body but is made up of blocks. Hence, a reinforced wall can break down when a vehicle crashes into it. The behavior of such a wall during vehicle collision depends upon the reinforcement material used for its construction, its design, and the method of the construction. In this study, the behavior of a reinforced retaining wall was analyzed while changing the reinforcement spacing using LS-DYNA, a general finite-element program. Eight tons of truck weight was used for the numerical analysis model. The behavior of a reinforced retaining wall under variable reinforcement spacing and positioning was analyzed. The results indicated that the reinforcement material was an important resistance factor against external collision load.
