Question
A (3 m x 8 m) footing is designed for a multistory
building; the footing is constructed at a
depth of 3m below the ground surface; the
foundation is subjected to a stress of 110 kN/m
Bedrock layer is located at 35 m below G.S.
saturated and dry unit weight of the soil is 21
kN/m3 and 17 kN/m3 respectively.
Find The borehole spacing and The number of
boreholes for a square area of 144 m and then
The depth of the borehole required for the site
investigation.
