Soil Reinforcement and Geosynthetics
ثبت نشده
چکیده
In the context of sustainable development which is a balancing act between the fulfilment of human needs and the protection of the natural environment, the use of natural fibers such as coir in geotechnical applications is desirable. Reinforcing the soil with coir fibers/coir geotextiles is a cost effective solution to the ground/soil improvement problems. The effects of fiber parameters on the strength, stiffness and compressibility behaviour of soil were studied in detail. The effect of coir fibers on swell response of expansive black cotton soil was also studied in terms of percentage swell vs. time variation for various fiber contents. Results showed that inclusion of fibers increases strength, stiffness, reduces the compressibility and swell potential. The evaluation of hydraulic behavior of coir fiber reinforced soil is another area, in which studies were carried in detail. It is observed that addition of fibers reduces the seepage velocity of plain soil considerably and thus increase the piping resistance.

Reinforced soil with geosynthetics – hands-on learning (PBL) using sand and paper
An elective module on geosynthetics was designed and made available to Civil Engineering students (5 years’ integrated masters). This paper reports a hands-on activity using sand and paper, adopted as part of a problem-based learning (PBL) model and the feedback collected in 2011/2012 using questionnaires. The model and its main features are briefly described, particularly the problem on soil r...

Geosynthetics have become well established construction materials for geotechnical applications in most parts of the world. Because they constitute manufactured materials, new products and applications are developed on a routine basis to provide solutions to routine and critical problems alike. Results from recent research and from monitoring of instrumented structures throughout the years have...
متن کاملRecent Developments in Ground Improvement Techniques - A Review
In recent years rapid development of infrastructures in metro cities compounded with scarcity of useful land and compelled the engineers to improve the properties of soil to bear the load transferred by the infrastructure e.g Buildings, bridges, roadways railways etc. The engineering techniques of ground improvement are removal and replacement, pre-compression, vertical drains, in-situ densific...
متن کاملGeosynthetic Reinforcement of Sand-Mat Layer above Soft Ground
In order to improve the bearing capacity of soft ground for the purpose of getting trafficability of construction vehicles, the reinforcement of geosynthetics for sand-mat layers on soft ground has often been used. As the strength of the geosynthetics increases, and the sand-mat system becomes stronger, the bearing capacity of sand-mat systems will be increased. The depths of geosynthetics, rei...
متن کاملEvaluation of Geosynthetic Forces in GRSRW under Dynamic Condition
Geosynthetics have proved to be suitable for reinforced soil retaining walls. Based on the increasing uses of geosynthetic reinforced soil systems in the regions, which bear frequent earthquakes, the study of dynamic behavior of structures seems necessary. Determining the reinforcement forces is; therefore, one of the most important and main points of discussions in designing retaining walls, b...
