| description | The distribution of the equivalent load in the analysis of the reinforcement of an embankment load transfer
platform on a soft soil reinforced with columns has an impact on the behaviour of the membrane modelling
this reinforcement. Depending on the calculation model, triangular, uniform and inverse triangular distributions
are commonly used. The paper analyses the behaviour of the membrane under the influence of 11 different
load distributions. For all distributions, deflection curves and diagrams of tensile forces, deformation and
the angle of rotation of the membrane were determined for the task of modelling the full-scale experiment.
An analysis of the influence of the subgrade reaction modulus (k value) of the soft soil between the columns
and the reinforcement stiffness on the membrane behaviour was also carried out. It was found that the adoption
of one of the load distributions as suitable in every design situation is not always justified. As a result
of the analyses, it has been shown that increasing soil stiffness (k value) significantly changes the nature of
the function of deflection, deformation and normal force in the membrane, and this change depends on the
distribution of the equivalent load. |
