Abstract: Abstract In order to reduce the test error when geotextile expansion rupture caused by foil deformation, a testing program of expansion rupture performance of geotextile based on foil correction was proposed. The graphs of system testing which were software flow chart of the total system and hardware block diagram were shown in this paper. The system uses motion control card to control the motor drive section, the signal acquired by the sensor was sent to data acquisition card, then, was sent into the computer by processing, the data obtained was processed by digital filter, data and graphs was displayed real-time during the testing process. Test data were given by this paper, and the results were analyzed, the results demonstrate the system reduce test error effectively when geotextile expansion rupture, it possesses practical significance.

Key words: geotextile , expansion rupture performance , disk correction , motion control card , data acquisition card
