“…In the dry pluviation method, the density of the samples depends on the deposition intensity (DI), height of fall (HF), uniformity of raining sand, the opening width of the curtain in the curtain technique, the porosity of diffuser, particle size, and other parameters (Butter eld and Andrawes 1970; Rad and Tumay 1987;Vaid and Negussey 1988;Lo Presti et al 1992Fretti et al 1995;Lagioia et al 2006;Choi et al 2010;Raghunandan et al 2012;Dave and Dasaka 2012;Gade and Dasaka 2015;Hariprasad et al 2016;Srinivasan et al 2016;Tabaroei et al 2017). In general, an increase in DI leads to a decrease in the density of the soil specimen because of with increase DI, The grains collision with each other increase and the grains farther apart so the density decreases.…”

Dry pluviation is a technique applied for preparation of sandy soil samples for physical modeling. In this method, soil particles rainfall in the mold after passing through the mesh with certain opening sizes. In this study, a dry pluviation device was designed and manufactured to examine the effect of shutter properties including the hight of fall (HF), deposition intensity (DI), and gradation on relative density (RD). The results indicate that HF and DI have a direct and indirect relation with RD, respectively, but RD is constant for HF ≥ 1200 mm. In order to investigate the impact of shutter properties on DI and RD, α ratio (total area of the shutter holes to the area of the deposition surface) was defined and a linear relationship is proposed between DI and α. The results revealed an indirect relation between RD and α, but for α ≥ 0.130 RD is constant. In order to assess the simultaneous effect of grain size and shutter properties on RD, an independent grain size variable (i.e., α/D50) was defined and a linear relationship was established between α/D50 and RD. The results showed that the variable α/D50 can be considered as a useful criterion for designing a shutter to reconstitute sandy soils with different gradations.

“…Therefore, the air-pluviation of the sand particles through a curtain rainer system at a HF of 100-600 mm is likely to be within the zone of HF control, which significantly affects the impact velocity of sand particles and at higher values of HF appears to be within the DI control zone. These observations are in good agreement with the observations of previous studies (Vaid and Negussey 1988;Stuit 1995;Choi et al 2010;Dave and Dasaka 2012;Srinivasan et al 2016). Choi et al (2010) showed that by using a porous plate the variation in RD for HF ¼ 100-400 mm is relatively high, and after that the DI changes the RD values.…”

Sand pluviation is a method used to prepare a model sand specimen to carry out some particular laboratory tests such as static and dynamic tests on footings, retaining walls, piles, as well as calibration of static and dynamic penetrometers. Preparation of uniform reconstituted sand specimens of required density is a prerequisite for obtaining reliable results. In this paper, two rainer systems, which are capable to prepare homogeneous sand specimens, are introduced. The first is a rainer system with a perforated plate and the second is a portable curtain rainer system. The portable curtain rainer system essentially consisting of a sand storage, flexible hose, a hopper, rigid tubes, and curtain with different opening widths. This study aims to reach a better understanding of the effects of deposition intensity (DI) and height of fall (HF) on the relative density (RD) of reconstituted sand specimens. The uniformity of the sand bed is verified by measuring the relative densities of 20 samples at different locations of the tank. By using a portable curtain rainer system, large uniform sand specimens with a wide range of RD ¼ 23-96% can be achieved. The results demonstrate that at a lower value of HF, the variation of RD is significant, while it has an insignificant effect on RD for values of HF ≥ 600 mm. Furthermore, in order to achieve a dense to very dense sand bed, the DI should be controlled. It was also observed that both systems significantly improve the horizontal and vertical homogeneities of the sand specimens. With an increase in the RD of reconstituted sand specimens, higher repeatability of uniform pluviation was achieved.

“…The corresponding values for the frequencies of magnitudes 1 Hz, 3 Hz, 5 Hz, 10 Hz and 15 Hz were 0.02 %, 1.99 %, 2.05 %, 2.01 % and 1.93 % respectively. These test results of face displacement response are partially similar to the (Krishna & Latha, 2007;Srinivasan et al, 2016;Suzuki et al, 2015). Figure 10 shows the effect of frequency for fixed base acceleration (0.1 g) and surcharge (19 kg) on acceleration amplification, strain and pore water pressures.…”

“…Moreover, it may be damaged due to the softening of soilfoundation (Ering & Sivakumar Babu, 2020;Krishna & Latha, 2007;Kumar et al, 2020;Latha & Krishna, 2006;Zhou et al, 2020). The Soil and Structure Interaction (SSI) system was considered in this experimental study, to simulate actual soil-foundation (Bullock et al, 2019;Çelebi et al, 2019;He & Jiang, 2019;Hore et al, 2020;Srilatha, et al, 2013;Srinivasan et al, 2016). Soft soils in Dhaka, Bangladesh were used to build the soilfoundation.…”

The main objective of this research was to model the zonation of wrap faced embankment on soft clay foundation, by applying a shake table test. Also, to investigate the dynamic behaviors of clay soil, such as acceleration amplification, displacement and pore water pressure of wrap faced embankment. This was done with respect to changes in frequencies of 1 Hz, 3 Hz, 5 Hz, 10 Hz, 12 Hz and 15 Hz respectively. Constant acceleration (0.1 g) and surcharge (19 Kg) were applied by using a laminar box, placed on a shake table testing machine. The main elements of this research were the laboratory test, which was used for preparing reconstitute soil samples, and wrap faced embankment with frequency arrangement. After applying all test parameters, dynamic parameters were increased by rise in elevation with respect to frequency. The result shows that the maximum dynamic parameters were found at the frequency of 10 Hz. It is beneficial to the relative performances of the wrap faced embankment, which is the updated design parameter.
