17、g and preparation of test specimens 3 Principle The hydrostatic pressure supported by a dry geotextile is a measure of the opposition to the passage of water through the geotextile. A specimen is subjected to a steadily increasing pressure of water on one face, under standard conditions, until penet
18、ration occurs. The pressure, at which water penetrates the geotextile, is noted. The water pressure may be applied from below or from above the specimen The chosen alternative should be stated in the test report. The result is immediately relevant to the behaviour of geotextiles which are subjected
19、to water pressure for short or moderate periods of time. The method is primarily intended for low permeability geotextiles. 4 Apparatus 4.1 The apparatus used for the test should be designed to comply with the following conditions. 4.1.1 It should be possible to clamp the circular specimen of geotex
20、tile in such a way that: - it is horizontal and not bulging; - a circular area of the specimen of (1 O0 - no leakage of water takes place at the clamps during the test; - the specimen does not slip in the clamps; - any tendency for penetration to occur at the clamped edge of the specimen is minimise

Two examples of apparatus are shown in figure 1. 4.1.2 The water in con
22、tact with the test specimen shall be distilled or fully deionized water maintained at (20 k 2) OC. If the apparatus used is of the type in which the water is contained in the testing head and rises to come into contact with the specimen, the surface of the water in the testing head may be cleaned in
