PST09, thank you.
In Tomlinson's book there is an annotation that "the zone of the disturbance of the soil occurs only within a radius of a few pile diameters around and beneath the individual pile, whereas the soil is significantly stressed to a depth to or greater than the width of the group"...
Thank you, Doc09, for your answer. I agree with you as it concerns for the settlements, but my problem is the capacity of the row. Is it equal to the sum of capacities of individual pile or not?
We have a single pile with diameter D and an estimated ultimate skin friction resistance equal to Qf and base resistance equal to Qb.
My question is: if we have one row of n=20 piles in distances equal to 1.2*D, which should be the total skin resistance and base resistance of the row?
Whould it...
According to din 4014 the min pile's embedment depth in the bearing stratum is 2.5m.
So my question is: if the bearing stratum has an undrained strength cu=150 kN/m2 should the pile be embedded also 2.5 m or not? Note that the bearing layer extend to a large depth.
