Gravelly soils are not well represented in current semi-empirical liquefaction procedures, which raises the question of whether state-of-the-practice evaluation methods based on sands applicable to gravelly soils. This paper investigates applicability Cone Penetration Test triggering and settlement procedures case histories well-graded reclaimed soil at CentrePort, New Zealand. Sensitivity stud...

The focus of this research is to investigate the effect water content and sand grain size on green compression strength a greensand casting mould mixture. Grain major determinant core surface finish product. Water influences efficiency binder which bentonite clay in bonding particles thus improving strength. objective study specimen prepared by mechanical grading graded into three sizes are 425...

Dry and moist tamping methods are widely used for the investigation of sandy soil liquefaction. However, effect these two tamping-based reconstitution on composite liquefaction behavior have been rarely assessed. In this study, dry were assessed using loose silica sand matrix (HN31) containing various amounts non-plastic silt particles (C500), by performing a series undrained triaxial compressi...

Complex life cycles have evolved independently numerous times in marine animals as well as in disparate algae. Such life histories typically involve a dispersive immature stage followed by settlement and metamorphosis to an adult stage on the sea floor. One commonality among animals exhibiting transitions of this type is that their larvae pass through a 'precompetent' period in which they do no...

in this paper we introduce the notions of uniformly quasi-primary ideals and uniformly classical quasi-primary submodules that generalize the concepts of uniformly primary ideals and uniformly classical primary submodules; respectively. several characterizations of classical quasi-primary and uniformly classical quasi-primary submodules are given. then we investigate for a ring $r$, when any fi...

In this study, the performances of sand piles in Istanbul's Bağcılar and Zeytinburnu districts has been analyzed using Finite Element Method (FEM). Single group (triple) with various length/diameter ratios (L/D) were placed water-saturated soft clay soil. Sand modeled L/D (10, 5.71, 8.57). The distance between was chosen as 2 meters effect also investigated. A uniformly distributed load 162 kN/...

Abstract One of the methods of increasing soil resistance against failure is soil reinforcement using geosynthetics. Soil-geosynthetic interactions are of great importance and are affected by friction and adhesion at their interface. Soil gradation, contact surface roughness and geotextile density are among the factors affecting soil-geotextiles interaction this study, to investigate the eff...

This study presents micromechanical finite-element FE and discrete-element DE models for the prediction of viscoelastic creep stiffness of asphalt mixture. Asphalt mixture is composed of graded aggregates bound with mastic asphalt mixed with fines and fine aggregates and air voids. The two-dimensional 2D microstructure of asphalt mixture was obtained by optically scanning the smoothly sawn surf...
