Bi-directional static loading test adopting load cells is widely used around the world at present, with increase in diameter and length of deep foundations. Some new load cells, test procedure, and construction technology were adopted based on the applications to different deep foundations. The paper presents the results of the bi-directional static load testing of a 1200mm diameter bored pile was designed for a load of 450 tons using a single level of S-cell. The length of the pile is 56.225m. The bi-directional static load testing method has proved advantageous over the conventional pile load testing methods in many aspects. This case was analyzed using finite element program PLAXIS 2D. The self-weight of the upper pile segment was taken into acccount. The equivalent top-load curve is used to illustrate as if the pile loaded from the pile head such as conventional head-down test. Comparison are presented between the results obtained when analyzed in PLAXIS and when field test is done.
