the geo-textile fabric utilization in Dawa delta,Liaoning Province in the flood prevention-shore protect-ing projectwas introduced.Byndoor test,the mechanical characteristic,the permeability and the counter-permeability were studied.The testing resultreveals that the standard permeation apparat us can be substi tuted by non-standard permeation apparatus to conduct the experimental research.Because the non-standard permeation ap-paratus is larger in size and is mo re similar with the real engineering practice,itives better to simulate the engineer-ing condition and is more useful to investigate the defensive project with experimental measures.
