Soil Mechanics and Foundation Engineering Aims and scope

Conclusions

1. From the data for the full-scale static tests of piles 6–22 m long, it was found that as the ratio ℓ/d increases, the load transmitted through a pile underreaming having the same size decreases proportionally.

2. The limit strength at the foot of piles over 10 m long cannot be determined by means of analytical strengths depending only on the depth h and the liquidity index IL but which do not depend on the ratio ℓ/d.
