“…Iskander and Liu (2003) also conducted a tri-axial test to analyze the properties of amorphous silica powder. It proved the same conclusion that the properties of amorphous silica powder are similar to those of the natural clay (Pillai et al, 2013;Cai et al, 2018).…”

This article introduces the uses of transparent synthetic soil for geotechnical problems using optical system, including transparent materials, sample preparation, geotechnical properties, experimental methods, and applications in physical modeling. Four typical kinds of transparent synthetic soil are shown and compared. For amorphous silica powder, normally the consolidated amorphous silica has a higher normalized strength but a lower modulus than the natural clays. For amorphous silica gels, the stressstrain behaviors are consistent with the typical stress-strain behaviors of sand for both dense and loose conditions. For fused silica, it has a higher shearing strength and higher modulus than the natural sand does; the deviatoric stress increases with the confining pressure, but the stress-strain curves of fused silica and the natural sand are particularly similar. For glass sand, with increasing of the relative density, the strainstress relationship varies from strain hardening to stress softening, while its failure form is essentially the same as that of standard sand. According to the geotechnical properties of four typical materials of transparent synthetic soil grain, they are used to simulate different conditions and analyze practical engineering problems in different physical model tests. The process included the generation of a speckle pattern created by the interaction of laser light with transparent particles. Using digital image processing technology, speckle patterns can be obtained and used to calculate the displacement field. By utilizing this optical system, transparent synthetic soil can be used to nonintrusively investigate internal soil deformation, flow problems, and ground movement in physical model tests. Finally, both the advantages and disadvantages of the transparent soil experimental technique are analyzed.

“…For land reclamation projects, dredged marine clay or sediments are often stabilized at a lower cement contents (<10%) (Maher et al 2007;Nakano and Sakai 2013;Pillai, Bushra, and Robinson 2013;Bhuria and Sachan 2014). Numerous theories and frameworks have been proposed to model the behaviour of cement treated clay such as extended critical state concept (Kasama, Ochiai, and Yasufuku 2000), modified cam-clay model with associated flow rule and isotropic hardening (Vatsala, Nova, and Murthy 2001), structured cam clay model (Liu and Carter 2002;Carter and Liu 2005;Horpibulsuk et al 2010), modified structured cam clay model , cemented clay model (Liu et al 2006;Liyanapathirana, Liu, and Carter 2010), bounding surface model (Pillai, Bushra, and Robinson 2013) etc. Most of these models are developed on the basis of modified cam clay (Roscoe and Burland 1968) which requires the critical state parameters such as slope of the normally consolidated line (λ), slope of the swelling line (κ), specific volume value in the critical state line at p' = 1 kPa (Г), specific volume value in the normal compression line at p' = 1 kPa (N), slope of the critical state line (M) as the input.…”

The present paper discusses the stress-strain behaviour and critical state parameters of dredged Chennai marine clay stabilized with low cement content (2.5-10%). Series of one dimensional consolidation test and consolidated undrained triaxial tests are performed on the cement stabilized dredged Chennai marine clay to evaluate the critical state parameters (λ, κ, M, Г, N) for varying cement contents and curing days. The results show that the slope of the critical state line Downloaded by [New York University] at 05:38 14 July 20152 M increases with an increase in cement content. The parameter λ for treated marine clay increases up to a cement content of 7.5% followed by a reduction. The parameter κ decreases with the addition of cement content. Finally empirical formulations are proposed to predict the critical state parameters as the functions of cement contents and curing days.
