Improving the Gypseous Soil Bearing Capacity Using Geotextile Reinforcement Under Dry Condition
Gypseous soil is one of the problematic soils and greatly affects the stability of the engineering structures, especially in Iraq. The main geotechnical problem of this soil is the significant reduction of its bearing capacity upon loading and/or wetting processes due to the dissolution of gypseous cementing bonds. This study aims to improve the soil's bearing capacity by using geosynthetics material in single, double, and triple distribution patterns. The gypseous soil samples were brought from a site near Sawa Lake by coordinates (31°18′42.83″ N, 45°00′49.36″ E) in Al-Muthanna Governorate with gypsum content of 37.35% forms about 3.0 m high under the ground surface. The Soil-Model apparatus of dimensions (60 × 60 × 50) cm is used, while the proposed square footing dimensions are (10 × 10) cm. The main test program investigates the bearing capacity before and after the soil reinforcement with the geotextile layers. The results showed a considerable increase in bearing capacity and the increase of volume change when using the triple phase pattern with the allowable bearing capacity increase for reinforced gypseous soil, especially with the increasing reinforcement layers at the triple reinforcement pattern. The depth of the geotextile layer with the soil mass has a significant effect on the magnitude of the bearing capacity and decreases the settlement. The improvement proportion of soil bearing capacity using Geotextile Reinforcement at dry state is ranged 20–90% for relative densities 30 and 60% and different reinforcement patterns.
