Research ArticleOpen accessIn the keywordsInfiltration Characteristics of Granitic Residual Soil of Various Weathering GradesFaisal H. Ali, Bujang B.K. Huat, T. H. LowThis study presents the result of a field study on the infiltration characteristics of cut a slope in granitic residual soil of various weathering grades. Granitic residual soil of weathering grade IV is found to have the highest infiltration rate. Water infiltration is found to increase from grade VI to IV and decrease from grade IV to grade III. Water … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 6,761 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCollapsibility and Volume Change Behavior of Unsaturated Residual SoilAzlan A. Aziz, Faisal H. Ali, chioong F. heng et al.Residual soils occur in most countries of the world but the greater areas and depths are normally found in tropical humid areas. In these places, the soil forming processes are still very active and the weathering development is much faster than the erosive factor. Most residual soil exhibit high suctions for most of the year. The absence of positive pore … …American Journal of Environmental Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 7,121 accessesView PDFCite
Research ArticleOpen accessIn the abstractHydro-Mechanical Constraints and Deformations in Road Embankments Using Unsaturated Low-Swelling SoilSoumaïla Gandema, Marcel Bawindsom Kébré, Rimyalegdo Kiébré et al.In this paper, we present the results of a simulation of the evolution of stresses and deformations in a road embankment using unsaturated low-swelling soil under hydro-mechanical pressures, modeled with the finite element code Code_Bright. We assume that this embankment, which supports asphalt, follows the Barcelona Thermo-Elasto-Plastic model (BBM-TEP). This model describes the Thermo-Hydro-Mechanical (THM) behavior of unsaturated fine soils … …American Journal of Applied Sciences, Vol. 22, Issue 1 · 16 Nov 2025 · 2,741 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Investigation on Geomechanical Properties of Tropical Organic Soils and PeatBujang B.K. Huat, Afshin Asadi, Sina KazemianProblem statement: Organic soils and peat were believed to be geotechnically problematic due to their very high compressibility, very low shear strength and difficult accessibility. Although conventional soil mechanics theory could be applied to the soils, it was found that important anomalies existed which required special considerations. Correlations between geomechanical parameters for the soils were known to be important for … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 10,172 accessesView PDFCite
Research ArticleOpen accessIn the abstractIdentification of Shear Band using Elastic Shear Wave PropagationT. Nachiengtai, W. Chim-Oye, S. Teachavorasinskun, W. Sa-NgiamviboolLocalization in soil under high stress level is usually investigated using some indirect measures, e.g., X-ray diffraction method. In the present study, the propagation velocity of shear wave was used to detect localization in sandy soil. Firstly, the general expression to exhibit the stress and density dependencies characteristics under consolidation and triaxial testing conditions of the tested soil was proposed. … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2008 · 6,794 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization and Geotechnical Properties of Penang Residual Soils with Emphasis on LandslidesFauziah Ahmad, Ahmad Shukri Yahaya, Mohd Ahmadullah FarooqiThe predominantly hilly terrain of Penang Island combined with average maximum daily temperatures ranging between 27-35°C and peak rainfall as high as 647 cm makes the overall area potentially susceptible to landslips. Over the recent past construction industry has shown a rapid growth mainly due to increase in the inflow of international tourists and other economic reasons. Eventually, the magnitude … …American Journal of Environmental Sciences, Vol. 2, Issue 4 · 31 Dec 2006 · 8,230 accessesView PDFCite
Research ArticleOpen accessIn the abstractFabric Behavior of Sand in Post-liquefactionSeyed Amirodin SadrnejadAn anisotropic plasticity model for post-liquefaction of the undrained behavior of sand is presented. The model incorporates the critical/steady state concept that postulates the existence of a state where sand continuously deforms at a certain constant effective stress depending two main parameters of both initial bulk parameters (void ratio or relative density) and the stress level (mean stress). The local … …American Journal of Applied Sciences, Vol. 2, Issue 12 · 31 Dec 2005 · 6,409 accessesView PDFCite
Research ArticleOpen accessIn the abstractField and Laboratory Suction- Soil Moisture Relationship of Unsaturated Residual SoilsBujang B.K. Huat, Faisal H. Ali, A. AbdullahSoils located above the groundwater table such as residual soils are generally unsaturated and possess negative pore-water pressures. A soil-water (moisture) characteristic curve (SWCC) that relates the water content of a soil to matric suction is an important relationship for the unsaturated soil mechanics. The SWCC essentially shows the ability of an unsaturated soil to retain water under various matric … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 7,038 accessesView PDFCite
