DURABILITY OF PLASTIC FLAPPED SOIL BAGS

Abstract

Landslides are extremely damaging to humans and property. The application of flapped soil bags to prevent and improve soil slope stability is one of the appropriate methods in this regard. The flapped soil bags are designed with a wing section to strengthen the bond between them, and implementation is not complicated. The flapped soil bags are considered a temporary structure therefore in long-term applications, the durability of the winged sacks is required. This research presented the results of two developed models of the winged sack: A) original flapped soil bag made of (HDPE/PP) B) flapped soil bag made of recycled plastic. The laboratory tests include tensile test, puncture tests, effect of exposure using fluorescent UV condensation apparatus and scanning electron microscopy. The test results illustrate the long-term trend of the engineering properties of flapped soil bags in each of the above models and the limitations on the application of flapped soil bags in geotechnical engineering application.
