Revetment Geotextile Filter Subjected to Cyclic Wave Loading

Chew, S. H. / Zhao, Z. K. / Karunaratne, G. P. / Tan, S. A. / Delmas, Ph. / Loke, K. H.

Geotextiles have been extensively used in hydraulic structures as revetment filters subjected to wave loads. The alternating flow through the geotextile creates a flow regime very different from the uni-directional flow condition that has been extensively studied. The stability of the revetment system depends on many factors, such as the hydraulic properties of geotextile, the initial placement condition and particle size distribution of the subsoil, and the intensity of the wave loads. A new laboratory apparatus has been used to investigate the influence of the hydraulic conditions on the behavior of soil-geotextile interaction and the stability of the revetment system. One series of tests has been conducted simulating cyclic flow conditions normal to the soil-geotextile interface. Preliminary test results are presented and discussed in this paper.
