Soil-structure interaction analysis of beams resting on multilayered geosynthetic-reinforced soil
Kousik Deb

 
Abstract     [Full Text]
    In this paper, soil-structure interaction analysis has been presented for beams resting on multilayered geosynthetic-reinforced granular fill-soft soil system. The soft soil and geosynthetic reinforcements are idealized as nonlinear springs and elastic membranes, respectively. The governing differential equations are solved by finite difference technique and the results are presented in nondimensional form. It is observed from the study that use of geosynthetic reinforcement is not very effective for maximum settlement reduction in case of very rigid beam. Similarly the reinforcements are not effective for shear force reduction if the granular fill has very high shear modulus value. However, multilayered reinforced system is very effective for bending moment and differential settlement reduction.
 
Key Words
    beams; flexural rigidity; multilayered geosynthetic reinforcement; soft soil; soil-structure interaction.
