For problem 3, the soil type is given at different depths and a loading of 100 kips is given per columns, a max differential settlement allowed is 1 inch. The best most economical type of foundation stated is drilled piers or driven piles.
How is this chosen?
Is there some type of thumb rule geotechs use to decide the type of foundation?
Or is it that, when in doubt just say 'drilled piers' I know they work for just about any soil type but may not be the most economical solution. In this case the water table was hit at 10 feet.
Also, in the main difference between drilled piers and driven piles, the construction method? They function in a similar way correct? by friction or by end rock anchoring?
Thank you so much!
