| Abstract | The performances of bored, driven and auger press pile
in Bangkok subsoils are evaluated by comparing their skin
frictions of piles embedded in clay, end- b earing resistance
of piles having tips in sand and the settlements based on the
soil-pile Elastic ' s Modulus <Es) estimated by using POULOS &
DAVIS <1980)' s method. The study shows that the developed
skin friction in stiff clay of all pile types is not much
different and the developed end-bearing resistance of the
piles having tips in sand, in this study, vary depending upon
the pile construction type s . The end - bearing capacity of
driven pile yields the value 2 -3 times higher than that of
bored pile. While the " equivalent" end-bearing resistance of
the auger press pile is nearly equal to that of bored pile.
The skin friction of bored pile proposed by MEYERHOF (1976)
is used to calculated the shaft resistance in sand of both
the bored and auger pile and the Es values of bored piles
penetrated both in clay and sand are very high due to the
effect of their large diameters. At the same working load, Es
of driven piles both penetrat e d in clay and sand are higher
than that of auger pile . The auger press pile settlement is
larger than that of driven pile and bored pile when the pile
dimensions are the same . Es also appears to be dependent more
on the size and the construction technique of the pile than
the pile tip's material. This conclusion is from data of pile
having approximately the same depth range C 25 to 35 m> .
The study of the performance of the auger press pile i s
concentrated on the consequence of the construction
technique. Auger press piling technique performed in clay
seems to yield less effect on the pile capacity, compared to
that performed in the sand . But its effect on settlement
behaviour is clearly shown for both piling in c lay and sand.
The empirical soil mechanics method for the estimation
of the capacities of the three pile types is proposed . Good
correlations are obtained in the predicted failure loads
compared to the capacities obtained from loading tests. |
