“…For the subgrade treated with the sand cushion, the settlements recorded after stabilization under the first-, second-, third-, and the fourth-stage loads were 109.39 mm, 122.86 mm, 130.05 mm, and 137.86 mm, respectively, which were greater than those of the soilbag-treated subgrade under corresponding loads. Such differences in settlement are attributed to the staggered arrangement of the soilbags in the upper and lower layers, which have the effect of spreading the stresses, enabling the vertical stresses from the upper layers to be more uniformly distributed to the base [33]. From these observations, it is inferred that the soilbag-treated subgrade exhibited a superior bearing capacity compared to the sand cushion-treated subgrade.…”

This research addresses the characteristics of soft soil subgrades treated by soilbags filled with excavated clayey soil. We evaluated of the strength and deformation modulus of soilbags containing excavated soil using unconfined compression tests. In addition, the drainage consolidation characteristics of soilbag-treated subgrades were investigated via model consolidation tests. Furthermore, a practical application included the construction of a 100 m-long rural road subgrade with these soilbags. The field test and numerical simulation results included the surface settlement and pore water pressure during and after construction to validate the effectiveness of the soilbag treatment for soft soil subgrade. The results show that the soilbags significantly enhanced both the strength and deformation modulus of the soft soil, which met the design requirements after the soilbag treatment. The drainage attributes of the soilbag treatment were also found to support the consolidation process of the soft soil subgrade effectively. Notably, the pore water pressure diminished rapidly during the construction interval, which is beneficial to reducing the post-construction settlement. The settlement uniformity of the subgrade is good verification of the superiority of the soilbag-treated subgrades.

“…The shape of the sliding surface has influence over friction resistance between the soil bag layers Fan et al (12). Fan et al ( 13) study showed a containment constructed wall to analyze the slippage stability, and concluding that "the active soil pressure acts upon the wall built with sand bags on their final stage is not linear, but can be calculated from the strength balancing forces of a differential element".…”

Dentro de las estructuras de retención o contención, usadas ampliamente en la infraestructura vial, existe una gama amplia de posibilidades, como son las estructuras de gravedad convencionales (gaviones, criba, etc.), reforzadas, embebidas, anclajes, suelo estabilizado mecánicamente, entre otras. Dentro de ellas también, se encuentran las bolsas gigantes de geotextil, las cuales funcionan por gravedad usando material de relleno del sitio y demostrando un buen rendimiento ante la protección contra la erosión fluvial, marítima y en obras de protección o de contención para vías. Este artículo presenta la versatilidad de las bolsas gigantes de geotextil en la infraestructura vial, en la estabilización de terraplenes, taludes; y control de erosión fluvial y costera. Se presenta como estudio de caso a la zona de Bengala (kilómetro 21 de la vía Garzón – Neiva) y Túnel de Crespo (Cartagena – Colombia). La metodología utilizada para evaluar la evolución de la mejora con la intervención de bolsas gigantes de geotextil se realiza mediante el reporte de diseño, ejecución, seguimiento y control de la geometría del sitio de estudio. Las zonas intervenidas con bolsas de geotextil gigante presentan un comportamiento efectivo en la estabilidad del terreno, en el control de erosión y en la recuperación geométrica. A nivel cualitativo se logra evidenciar el proceso de restauración y estabilización de la costa y talud afectados, gracias a la intervención con bolsas de geotextil gigantes. A nivel cuantitativo se aprecia la estabilidad a largo plazo y la recuperación geométrica de las zonas intervenidas.

Plate Load Tests of Soft Foundations Reinforced by Soilbags with Solid Wastes for Wind Farms

Soilbags are expandable three-dimensional geosynthetic bags made from high-density polyethylene or polypropylene. This study conducted a series of plate load tests to explore the bearing capacity of soft foundations reinforced by soilbags filled with solid wastes based on an onshore wind farm project in China. The effect of contained material on the bearing capacity of the soilbag-reinforced foundation was investigated during the field tests. The experimental studies indicated that soilbag reinforcement with reused solid wastes could substantially improve the bearing capacity of soft foundations under vertical loading conditions. Solid wastes like excavated soil or brick slag residues were found to be suitable as contained material, and the soilbags with plain soil mixed with brick slag had higher bearing capacity than those with pure plain soil. The earth pressure analysis indicated that stress diffusion occurred through the soilbag layers to reduce the load transferred to the underlying soft soil. The stress diffusion angle of soilbag reinforcement obtained from the tests was approximately 38°. In addition, combining soilbag reinforcement with bottom sludge permeable treatment was an effective foundation reinforcement method, which required fewer soilbag layers due to its relatively high permeability. Furthermore, soilbags are considered sustainable construction materials with advantages such as high construction efficiency, low cost, easy reclamation and environmental friendliness while making full use of local solid wastes.
