The aim of the study was to characterize a variety of microstructure development-levels and geotechnical property sequences of the late Pleistocene-Holocene deposits in the Mekong River delta (MRD), and the paper furthermore discusses the influences of delta formation mechanisms on them. The survey associated the geotechnical engineering and the sedimentary geology of the late Pleistocene-Holoc...

In geotechnical engineering, direct simple shear (DSS) tests are used to determine strength and stiffness parameters of a material. DSS predictions constitutive model influence failure mechanisms in plane-strain, finite-element applications. this article, we introduce closed-form solution the Matsuoka–Nakai equivalent critical friction angle from stress normal data. order apply it clay hypoplas...

This paper describes the laterally confined consolidation of an Israeli clay following compaction and swelling on wetting, including measurement lateral stresses. The results tests are compared to those obtained during from initially slurried condition. In comparing compression expansion indices relative vertical, mean stress, it was found that they varied, depending initial, preparation condit...

The focus on glutamate neurotransmission presented in the October 2005 CNS Spectrums 1,2 was a turning point in the conceptualization of overconsolidational fear disorders, such as post-traumatic stress disorder (PTSD). We would like to draw attention to a potential confounding factor that can be controlled in future studies. Dietary free glutamate (DFG) is not only a common flavor enhancer (mo...

Abstract This paper presents a novel, exact, semi-analytical solution for the quasi-static drained expansion of cylindrical cavity in soft soils with fabric anisotropy and structure. The assumed constitutive model is S-CLAY1S model, which Cam clay-type that considers evolves plastic strains, structure gradual degradation bonding (destructuration) due to straining. involves numerical integration...

Suction piles are used to ensure wellhead stability during natural gas hydrate production in the Shenhu area of South China Sea (SCS). Undrained shear properties clayey-silty sediments play a critical role analysis suction piles. However, it has not been fully studied. This study conducts series undrained triaxial tests on shallow SCS, and stress–strain curves under different overconsolidation ...

Up to now, the effect of strain rate on adhesive bond shearing resistance stiff clay, which plays a fundamental role in constitutive modeling such kind soils, remains unclear. This paper aims experimentally investigate dependency clay. Both undisturbed and reconstituted overconsolidated samples Merville clay from Flanders region north France are prepared with different overconsolidation ratios ...

Abstract A high-cycle accumulation (HCA) model predicting the of permanent strain or excess pore water pressure in clay under a large number load cycles is presented. Data from an extensive laboratory testing program on kaolin undrained cyclic loading has been analysed for that purpose. The influence amplitude, void ratio, stress overconsolidation ratio and frequency rates considered constituti...
