Pile deflection carrying lateral loads

Pile deflection carrying lateral loads

Pile deflection carrying lateral loads

(OP)
As per tomlinson book deflection at head of fixed headed pile is y=H(e+Zf)^3/(12EI)

Above is for single pile only Or can be use for group of piles connected with Pile cap ?

I am using this for 5 nos (1200mm dia) concrete piles connected with pile cap 2500mm depth. Pile spacing is 3600mm. I am calculating equivalent I(moment of inertia) and using above formula. Is it correct?


For above problem fixity depth is 30m. What is the maximum deflection permitted ?

Thanks
Nitin
