“…The stone column's diameter has been extended to 75 mm, and the number of geogrid layers within the blanket has increased to two layers. Extensive studies have been carried out on geosynthetic-reinforced soil systems [46][47][48]. However, there is no unified understanding of the failure mode of reinforcement, and few experimental investigations have been conducted on this topic [49].…”

“…Furthermore, Iraji (27) analyzed finn-byrne model for liquefaction of quay and cantilevered retaining walls. Monotonic and cyclic loads are two conventional loading types in various geotechnical problems (28,29). Previous attempts demonstrate that τs has a significant effect on shear resistance under monotonic and cyclic loading.…”

Mining Exploration, excavation, and construction are considered as mining activities which are recently growing dramatically. Therefore, utilizing the mining wastes with the least environmental damage is a significant concern. Tailings dams are one of the conventional solutions that store the extracted hazardous substances safely for water resources management and environmental protection. This reseach deals with the effects of monotonic and seismic loadings on silt-sized copper wastes existed in a tailings dam at Northwest Iran as a case study. Various values of initial static shear stress are performed using an automated cyclic triaxial system. Monotonic undrained compressive tests were performed with a relatively constant density and considering three values of 50, 100, and 150 kPa for mean effective stress. Depending on the first density of samples, applying a mean effective confining pressure of 100 kPa, increased the initial densities by 25 to 30% as compared to the initial condition.Moreover, the effect of initial shear stress ratio with three values of 0, 0.2, and 0.4 was evaluated. No peak point was observed for samples under α = 0, whereas, samples with α = 0.4 encountered a peak point before reaching to the phase transformation point. The results of cyclic experiments were used to evaluate capacity energy and residual pore pressure based on the strain energy approach. Cyclic tests on the samples were performed considering the shear amplitude of 0.75% and frequency of 0.3 Hz. It is shown that the most energy dissipation occurs at the first cycle possessing the highest stiffness. For α = 0, energy density increased from 474 J/m 3 to 1147.4 J/m 3 ; however, a more intense increase was measured from 682 J/m 3 to 5839 J/m 3 when α = 0.4. It is also found that applying initial shear stress has a pretty considerable influence on monotonic strength and the liquefaction resistance of silts. The increase of α from 0 to 0.4 yielded a linear increase in the shear strength of samples in the range of 20 kPa to 70 kPa. The results of this paper were then validated accurately through some previous studies.

“…One of the more common traditional structures, geosynthetic reinforced soil (GRS) walls are reinforced with either geotextile, geogrid, steel strip, or geo-strip in order to increase tensile strength. GRS walls have gained popularity from an environmental standpoint because of their increased flexibility, speed of construction, affordability, and potential for employing locally sourced materials [4]. Because they are affordable, quick and simple to construct, better acceptable to differential settlement, and more tolerant against seismic stresses, GRS walls have occupied a significant amount of area as retaining structures [5,6].…”

The flood hazard parameter of peak discharge and prolonged inundation due to change in dam regulation is estimated for a water front Geosynthetic Reinforced Soil (GRS) wall on the downstream of large dam. Dam regulation rule level is pre-emptying the reservoir with lower peak discharge to protect the expanding downstream city intruding the flood plain. Present study is to test the hypothesis that rule level has significantly changed peak discharge and inundation duration and also to estimate these two important parameters of flood hazard for different flood return periods. The methodology consists of three parts: first is the categorization of flood data according to major event of flood regulation, second is the distribution test and third is the estimation of design maximum peak discharge and duration of flood. The estimated value of peak discharge and flood duration clearly indicate the implication of dam regulation rule level; the estimated value of peak discharge for 200 years return period is 13.9 lakh Cusecs, which is lower than the flood discharge for year 1968, which was 15 lakh Cusecs, and the estimated flood duration for 10 years return period is 41 days. The most important finding of this study is the substantial increase in duration of flood due to implementation of rule level which will add one more flood hazard parameter for water front geotechnical structure that is prolonged inundation.
