100學年度研究獎補助論文[[abstract]]The load type influence on the filtration behavior of soil-nonwoven geotextile composite has been studied through a series of tests using an experimental apparatus designed specifically for the laboratory tests. In these tests, the soil-geotextile composite was formed by inserting a piece of nonwoven geotextile between a 5-cm thick soil and a layer of steel beads. One of the three load types, namely sustained load, pulsatory load, and compound load of pulsatory and sustained load, was applied to the composite prior to the filtration test. Water was allowed to flow through the composite from the soil into a drainage layer at various hydraulic gradients. The permeability value was extracted by using Darcy's law to characterize the filtration performance of the entire soil-geotextile composite.[[notice]]補正完畢[[incitationindex]]EI[[booktype]]紙
