...) serving as an alternative to a conventional compacted clay liner or as a means of augmenting the performance of a compacted clay liner as part of a composite liner system in the base of municipal solid waste landfills is examined. It is shown that basal reinforcement can be an efficient and effective...

... ABSTRACT: Ground support comprises a wide field of geotechnical engineering. Therefore some special topics are selected: Reinforcement and dowelling of soil and rock by nails, anchors, piles and jet-grouting. Thus, the ground becomes more or less a compound body which locally can be considered...

... ABSTRACT: Unpaved roads built over soft, weak subgrade have been used extensively in the Southeast Asian region as temporary site access roads, forest roads and low volume roads. Trafficking of vehicles on un-reinforced unpaved roads will cause severe rutting and mud-pumping problems...

...NEW APPROACHES TO REINFORCED EARTH CONSTRUCTION Konstantin Sh. Shadunts1, Oleg Y. Eschenko2 ABSTRACT The paper discusses the possibility of using the principles of bionics for designing reinforced earth embankments. Practical usage and novelty of proposed approach are shown on the example of number...

Recently developed geocomposite comprises a sandwich structure of both non-woven fabric in between woven fabric and has over the tensile strength of geogrids of woven fabrics and also having the drainage effect of non-woven fabrics. However, current design methods of nonwoven fabric-reinforced...

... the viewpoint of the ductility. For the same cement dosage, increasing fiber content or length significantly increased the ductility. The contribution of fiber length to the peaks showed opposite influence at different cement dosages. The enhanced behavior of reinforced alluvial soil due to fiber inclusion may...

... on level ground and consequently, the ultimate bearing capacity is reduced. Due to reduction in bearing capacity, it became necessary to strengthen the foundation soil. Since geojutes are abundant and cheaply available in tropical counties like India, it may be used for providing the reinforcement...

...LESSONS LEARNED FROM FULL SCALE TESTING OF GEOSYNTHETIC REINFORCED SOIL RETAINING WALLS Richard J. Bathurst1 and Dave L. Walters1 ABSTRACT The paper summarizes work by the writers that is focussed on a program of full scale model tests of geosynthetic reinforced soil walls carried out...

...A REVIEW OF THE DURABILITY OF SOIL REINFORCEMENT Kenneth C Brady1, Martin J Greene2 and David I Bush3 ABSTRACT This paper reviews the findings of the field studies undertaken by TRL and The Highways Agency (HA), over the last 20 years or so, on the degradation of metallic reinforcements...

... for reinstatement/repair were:- an earthworks solution; a half bridge; a full bridge; a reinforced fill slope; piled retaining structure; mechanically stabilised earth wall. The advantages and disadvantages of each of the options was assessed. The earthworks option required removal of up to 600,000m3...

... reinforcements. Evaluated results of laboratory and field pullout experiments for steel straps, geotextiles, polymers and nylon geosynthetics are summarised. INTRODUCTION Earth reinforcements are increasingly used in offshore/harbour structures, retaining walls, embankments, landfills, liners, foundations...

... ABSTRACT: After heavy rainfall at Kangchon-Ri in Korea on 27 July in 1996, an excavated and reinforced slope for condominium construction site was failed. To figure out the cause of the slope failure and to plan remedial works, investigation of rainfall, surface and subsurface geological...

... ABSTRACT: This paper presents the measured behavior of an anchored segmental retaining wall. A segmental retaining wall reinforced with steel bar-anchor block systems has been recently developed and implemented in Korea. In an attempt to understand the overall mechanical behavior...

... ABSTRACT: A method for predicting the pull out load Ð end displacement behaviour of geogrid reinforcement embedded in sandy soils using a nonlinear finite difference approach is presented in this paper. In this method, the soil was modelled as an elastic-perfectly-plastic Mohr-Coulomb type...
