Analytical study for double-layer geosynthetic reinforced load transfer platform on column improved soft soil

摘要: Abstract The objective of this study is to propose a reasonably accurate mechanical model for double-layer geosynthetic reinforced load transfer platform (LTP) on column soft soil which can be used by practicing engineers. developed very useful the behaviour LTP resting improved with conventional columns such as concrete columns, piles, and deep mixing columns. negligible tensile strength granular material in LTP, bending shear deformations compressibility shearing have been incorporated model. Furthermore, results from proposed simulating Kerr foundation are compared corresponding solutions when idealised Winkler Pasternak models. It observed comparison that presented tool better prediction multi layers geosynthetics, situation modelled foundations. parametric studies show spacing increases, maximum deflection normalised tension geosynthetics also increase. Whereas, decrease increasing thickness, stiffness subsoil, reinforcement. In addition, it use one stronger layer (e.g. 1 × 2000 kN/m) equivalent two 2 1000 kN/m) does not result same settlement reinforcement weaker layers.
