Use of Geocomposite as an Internal Drain in Levees Subjected to Seepage: Centrifuge Model Study
The main objective of this paper is to investigate the performance of levee sections at the onset of flooding and subsequent seepage with the help of centrifuge model tests at 30 gravities. Three levee sections were modeled viz. levee section without drainage layer, with horizontal sand drain and with horizontal geotextile drainage layer. The flood was simulated with the help of remotely operated in-flight flood simulator. Levee section without any horizontal drain or clogged drain was observed to experience a catastrophic failure. Horizontal sand drainage layer was found to be very effective to dissipate pore water pressure leading to the stability of a levee. The analysis of centrifuge test results shows that horizontal geotextile drainage layer is effective in ensuring stability of the levee section at the onset of flooding and subsequent seepage. An attempt has also been made to compare results obtained from centrifuge studies with seepage and stability analyses using SEEP/W and SLOPE/W software. Finally, this paper concludes the use of geotextile horizontal drainage layer as an internal drain in place of conventional sand drainage layer as a viable option for imparting economy to construction projects.
