Abstract

Studies show that in 80 percent of unsuccessful drainage projects, the reason is improper subsurface drainage envelope design and installation. Thus, proper envelope design and installation is more important than other subsurface drainage design parameters. Gravel envelopes which are generally used in projects has some limitations in prepation, transportation, installation. That's why the use of synthetic envelopes developed in some countries. Synthetic envelopes or GEOTEXTILEs have no problems such as the ones expressed above for gravel envelopes. In this study two kinds of NON-WOVEN synthetic envelops were made of polypropylene and polyacrile filaments, then an unstable soil with sandy loam texture was selected. After determining the properties of soil and GEOTEXTILEs, the best GEOTEXTILE was selected for this soil by PERMEAMETER testing. The results of GEOTEXTILE and gravel envelope investigation in compare with each other in soil-water tanks showed that the ratio of average outlet discharge of drains with GEOTEXTILE envelope to gravel with different hydraulic heads(30, 60 and 90 cm) were 0.83, 0.72 and 0.6 respectively. It shows that GEOTEXTILE discharge is lower than gravel. In addition, the resistance of GEOTEXTILE to water current is more than designed gravel envelop.
