A LABORATORY STUDY OF THE RETENTION AND FILTRATION CHARACTERISTICS OF GEOTEXTILE WRAPPED DRAINAGE PIPES --14TH ARRB CONFERENCE, 28 AUGUST - 2 SEPTEMBER, 1988, CANBERRA, ACT, AUSTRALIA; PROC. PARTS 1 - 8

A laboratory test has been developed for the evaluation of the mechanisms governing soil/geotextile drainage systems. The test is orientated toward applications that involve radial flow toward geotextile wrapped drainage pipes. The influence of any given soil, geotextile or drainage pipe combination can thus be studied. A description of the test apparatus and procedures is given. The results of a test program show that filtration behaviour is dependent on soil compaction conditions and the onset of a soil filter at the soil/geotextile interface. A comparison of various grades of a non woven geotextile showed only marginal variations in their performance. The impact of various drainage pipes were assessed and found to have minimal effect on the filtration system as a whole. The results are compared with data obtained from tests on geotextile discs located in a modified permeameter and good agreement was obtained. The validity of various retention and filtration design criteria was checked against test results and good agreement was observed (a). For the covering record of the conference, see IRRD no 808936.
