THE EFFECT OF HOLES ON THE TENSILE PERFORMANCE OF GEOTEXTILES

The article discusses the results of experimental investigations, performed according to ASTM specifications, on woven and unwoven geotextile samples with various percentages of reduction in cross-sectional area due to a central hole. Results from the tests, on Amoco Pro Pex Cef, in an 'ungaged' condition, are presented in a tabular and graphical form and can be used to estimate possible reductions in tensile strength due to holes. It was found that in general cuts, holes or perforations resulting in a less than ten per cent reduction in cross-sectional area should have little or no effect upon the strength of woven or unwoven textiles, with the possible exception of woven geotextiles loaded parallel to the direction of bias. It is recommended that in field conditions likely to produce punctures, either non-woven fabrics are used or else woven fabrics could be installed so that maximum tensile stresses are applied in the direction of the fill.
