For the deformation calculation in pile group, the force transfer path is used here. They consider +!z{5:
z4+k7a@jn
pile and soil inside of pile group work together and use the force transfering angle to decide the XKttZOiGT

under layers. The soil surrounding pile group area support the pile and soil inside of pile group. 8XzR

For the group pile capacity, they use individual pile and add the pile group effect. The idea just oCi=4#g%7

continue from single pile design. 4.h=&jz&

Different ways and ideas for two calculations, it is a little bit hard to understand. But both are correct. Q/I!}C4

BTW: in the beam design, the force transfer path also be used now in some countries.
