Numerical Modeling of Honeycombed Geocell Reinforced Soil

This abstract describes a study on the Hilla Canal regulator using the SEEP/W program. The study aims to simulate and validate hydraulic head values obtained from the field. It provides information about the soil properties and mesh sizes used in the simulation and the governing equation used in the SEEP/W program. The simulation results are presented in the form of observed and simulated hydraulic head statistical and computational data, including RMSE, ME, and Maximum Relative Error. The study concludes that the model's performance is good, with an efficiency of 99.999%, and that the comparison of observed and simulated hydraulic head values confirms the model's validity. Overall, the study demonstrates the accuracy and applicability of the SEEP/W program for modeling hydraulic systems.

“…In general, the inclination angle of anchors varies between (10-45°) with the horizon [23]. The angle (20°) was adopted in this research because it is close to the average rate above and was used by [24]. The suggested diameter of the anchors is (38.6 mm) with its specifications listed in Table 2.…”

Strengthening the Slope Beneath Bashtapia Castle at the Highest Expected Tigris River Level

This study has been achieved using Geo-Studio Finite Element Software in two sections. First, to study the changes in pore water pressure (PWP) within the soil layers below Bashtapia Castle at different water levels of the river Tigris. The effect of these changes was in focus to check the slope stability of the Castle. On the other hand, the second section was to increase the safety factor using slope reinforcement using different spacings and lengths of the anchor’s rods. Modeling output showed that the factor of safety (FS) decreased from 2.83 to 0.838 when the water level raised from 0 to 7 m above the bottom slope layer. Accordingly, anchor bars were introduced in the model, and the safety factor increased. The slope layers were treated and strengthened using reinforcing anchor bars at different lengths and numbers. In general, the analysis results showed the positive effect of reinforcing bars on the stability of the castle slope. The FS of the slope castle increases with the increased length and number of anchors to a certain value, and then there is no effect of this increase on the FS value.

“…A growing component of pavement system design and repair is the use of innovative technologies to improve pavement performance and service life. Numerous solutions have been proposed over the last three decades as systems that could improve pavement performance and stop current premature failures [10][11][12][13][14][15]. This study looks into the performance enhancement of an unpaved road that has been reinforced with a single layer of geogrid put at the soft subgrade/subbase interface and exposed to repetitive loading.…”

The current study examines how an unpaved road behaves when it is installed on top of a soft clay layer that's been strengthened at the subgrade/subbase interface with a single layer of geogrid type SS2 is used to reinforce a laboratory model, and cycling load is used to apply repeated loads to the model. Subbases with and without reinforcement over soft subgrade were built in a sizable test box. (1000 mm×1000 mm×1000 mm). The test results show that using a geogrid reinforcement layer enhances the number of cycles and stress distribution while decreasing displacement on the soft subgrade surface on reinforced models compared to similar unreinforced ones for the same rutting value (85 mm). The rate of increase in failure time is about (6.12, 3.7, and 1.7) for 150, 230, and 300 mm thickness, respectively. The rate of redaction in vertical stress is about (18, 12.5, and 7.1) % for 150 mm, 230 mm, and 300 mm thickness, respectively.
