Soft soil stabilization designs using geosynthetics
AbstractNumerous facilities are currently being constructed world wide on very soft soils using geosynthetics. Often the foundation soils are at such low shear strengths (often less than 5–10 kPa), that the geosynthetic reinforcement material clearly must be in the high strength classification. A series of design elements leading to the required geosynthetic strength, modulus, anchorage length and surface friction are illustrated in this paper, many with design charts. These quantitative design elements are then augmented by numerous qualitative considerations, such as fabric specific gravity, its stiffness, and the size and weight of the rolls.Finally, an attempt at integrating the above mentioned technical considerations into the actual fabric's manufacture is presented. A concluding flow chart showing each element along the entire design sequence is described which will hopefully aid in affording owners both a safe and economical solution for soft soil stabilization projects.
