pile raft foundation, load sharing

in my 3x3 model of pile raft foundation, modeled as volume elements and with distributed load 
I would like to know how I can know how the load is distributed, i.e. how much is for example the% of load that the slab takes, so Qraft / Qtot ,
also I would like to know about the graph for each pile of the normal effort as a function of depth, I get the forces from importing centerlines and then I select a pile
and I extract the table, but I see that at the same depth of -1m there are many values ​​and also at other depths there are two values ​​one soil and the other clus,
what does this mean?
