“…As seen from the studies in the literature, there is no unique value proposed for the reinforcement length. Furthermore, the reinforcement must have sufficient length and stiffness [26]. In this study the geotextile reinforcement length was 700 mm, to wrap each sand layer properly.…”

This research incorporates shaking table testing of scale wrap faced soil wall models to evaluate the seismic response of embankment. Currently the seismic designs of highway or railway embankment rely on little or no empirical data for calibrating numerical simulations. This research is working towards filling that empirical data gap. The specific purpose of the study was to evaluate the seismic response of constructed embankment model regarding the different input base accelerations with fixed frequency. A series of one-dimensional (1D) shaking table tests (0.05g, 0.1g, 0.15g and 0.2g), were performed on a 0.4 meters high wrap faced reinforced-soil wall model. Additionally, it was placed over 0.3 meters high soft clayey foundation. Predominantly, the influence of the base acceleration on the seismic response was studied in this paper. The physical models were subjected to harmonic sinusoidal input motions at a fixed frequency of 1 Hz, in order to assess the seismic behavior. The effects of parameters such as acceleration amplitudes and surcharge pressures on the seismic response of the model walls were considered. The relative density of the backfill material was kept fixed at 60%. The results of this study reveal that input accelerations and surcharge load had significant influence on the model wall, pore water pressure, and changes along the elevation. Acceleration response advances with the increase in base acceleration, so the difference being more perceptible at higher elevations. The pore water pressures were found to be high for high base shaking and low surcharge pressures at higher elevations. The results obtained from this study are helpful in understanding the relative performance of reinforced soil retaining wall under different test conditions resting on soft clay.

“…Roads are subject to the active influence of numerous natural and climatic factors (snowdrifts, moistening by precipitation, surface, and groundwater). These peculiarities of highway operation must be considered when designing the design line of longitudinal profile (setting of guiding working marks, checkmarks of culverts) and the roadbed [15][16][17].…”

Quantitative and qualitative changes in recent years in the road industry require new technological approaches to road construction. Today some of the most used materials in road construction are geosynthetics. Geosynthetics have become interesting engineering materials in a wide range of applications and geotechnical, environmental, hydraulic, environmental, and private developments. The paper presents the research on the load and operational condition of the test model of a road reinforced with different geosynthetic materials. Geogrid and geotextile were used in testing. High-strength geotextiles or geogrids can provide adequate embankment reinforcement when properly designed and selected. Both materials can be used equally well, provided with the requisite design properties. Under the influence of the load from transport, the filler used for the cells is compacted. Currently, there is a redistribution of load throughout the entire volume of the monolithic structure with the grid. The tests carried out showed that using geotextiles leads to a decrease in the settlement coefficient by 25% and the use of a geogrid -by 38%. In rural areas of Kazakhstan, where the road network is in poor condition due to weak soils, strengthening the roadway with traditional materials will require large sums of money. Reinforcing the soil of unpaved roads with geosynthetic materials will allow more rationally and at a lower cost to improve the performance of unpaved roads in rural areas of Kazakhstan.

“…Tavangar and Shooshpasha [18] carried out plate load tests with square plates of different sizes and studied the influence of the first layer depth, vertical spacing, and number of layers of geotextile on the ultimate bearing capacity of the foundation. Cicek et al [19] investigated the influence of the first reinforcement layer depth through indoor plate load test and finite element model analysis, and the effective depth of the first reinforcement layer is obtained. Ghosh and Bera [20] investigated the effect of the geotextile ties on the uplift capacity of anchors embedded in sand.…”

In order to analyze the uplift bearing capacity of transmission tower foundation in the geosythetic-reinforced aeolian sand, a series of simplified indoor modeling tests are carried out. A simplified reduced-scale foundation made according to the prototype and the uplift bearing capacity of transmission tower foundation in geosynthetic-reinforced aeolian sand is studied. Three kinds of reinforcement materials are embedded in the sand according to five ways of layout spacing. A total of 15 reinforcement schemes are tested. The results show that ultimate uplift bearing capacity of transmission tower foundation can be significantly improved by the reinforcement treatment of geotechnical materials in the aeolian sand. The type and spacing of reinforced materials also have a significant influence on the uplift bearing capacity of the foundation model in reinforced aeolian sand, and the effect of reinforcement works until the end of the loading process. The comprehensive effect is evaluated by the ratio of bearing capacity improvement and the total layer of reinforced materials. Based on the above results, the bearing mechanism of transmission tower foundation in geosynthetic-reinforced aeolian sand is elaborated and analyzed in detail.
