ABSTRACT

Field tests on instrumented piles are critical to the development and improvement of design methods for pile foundations. This paper presents results of full-scale loading tests on two steel H-piles driven into dense sandy deposits. The test piles, with the embedded length of 39.6 m and 55.4 m, respectively, have a design capacity of 3540 kN. Both piles were heavily instrumented, driven into very stiff strata and loaded to failure. The load transfer and settlement characteristics of the piles are examined for various loading levels. The magnitude and distribution of the shaft friction of the piles are analyzed using the principles of soil mechanics.

Keywords: capacity; field tests; sandy soils; piles.
