A STUDY OF SOIL MOISTURE BEHAVIOR AND STARBILITY OF GEOSYNTHETIC REINFORCED SOIL WALL UNDER RAINFALL CONDITION

Abstract

This research aims to present the influence of soil moisture behavior and stability of the Geosynthetic Reinforced Soil (GRS) Wall under rainfall conditions. GRS wall seepage and stability analysis under rainfall conditions were simulated based on field monitoring such as rainfall intensity, pore-water pressure, and soil moisture. This research simulated in highest rainfall intensity from field monitoring to create a seepage model and stability analysis. It reveals that after rainfall, water seeps through the backfill soil and effect to decreasing of a safety factor. This result can be used in terms of design work and maintenance of the GRS wall as a long-term benefit.
