Studying the effect of roughness on soil-geotextile interaction in direct shear test
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...
متن کاملEnhancement of Engineering Characteristics of Soil Using Jute Geotextile
Natural fibres such as jute were the forerunners of the man-made fibres used for centuries for making ropes and formanufacturing burlaps, sacks, hessian and carpet backing. But the use of jute products in civil engineering is relativelywidespread for such purposes as sand-bags for concrete curing, soil enrichment and protection. This research is concerned with the stabilization of fine sand usi...
متن کاملComparison of Fine Particle Clogging in Soil and Geotextile Filters
This paper addresses the differences in the extent of clogging associated with fine particle transport in soils and geotextiles. A common experimental set-up was designed for soil and geotextile filtration. Tests were conducted using a nonwoven, needle-punched geotextile filter sample permeated with fine particle suspensions under constant flow rate. The results were compared with those from si...
متن کاملNumerical Discrete Element Simulation Of Soil Direct Shear Test
One of the most common methods to measure soil mechanical properties (namely cohesion and internal friction angle) is direct shear box test. In this paper the development of a three-dimensional (3D) discrete element soil model for simulation of a cohesive soil’s direct shear test is presented. The aim was to calibrate the properties of the Hertz-Mindlin with bonding contact model available in E...
متن کاملFiltration Performance of Two-Layer Geotextile Systems
Nonwoven geotextiles are commonly used in filtration applications. For some applications, however, a nonwoven geotextile filter may not have the required mechanical properties to withstand deformations, and an additional woven geotextile is usually employed in design. While reinforcement is an important function expected from these two-layer geotextile systems, filtration is another function th...
