Bearing and deformation characteristics of geotextile-encased granular piles using recycled solid waste

This study introduces a novel geotextile-encased granular pile made from recycled solid waste. Through uniaxial compression tests, the effects of soil relative density, particle size, and geotextile tensile strength on pile strength and modulus were examined. Among these, geotextile tensile strength had the most significant impact. Particles larger than 3cm were found to reduce pile strength due to puncturing and crushing. Model tests in soft clay revealed that geotextile-encased solid waste granular piles outperformed traditional piles, achieving a 72% reduction in settlement and a 176% increase in pile-soil stress ratio. This enhanced design not only improves mechanical properties but also promotes economic savings and emission reductions, offering a promising solution for sustainable construction practices.
