Laterally loaded pile groups

Hi, I am Ramy, I am about to perform some analyses on laterally loaded pile groups in sandy soils, does anyone have any idea about the best constitutive model to use?, loading is static. And I am using PLaxis 3D foundations version 2.1 Regards, Ramy

I'm not exactly sure.  But here are some suggested constitutive models for you to investigate.



Dafalias Manzari (seems like this is for sand)

 Although, it looks like plaxis 3d only allows the mohr coulomb model, in which case you don't have a choice??

Hi Rami,

I think Cam-Clay is more suitable for Clay soils. Try Mohr-Coulomb too.
