Bi-Directional Static Axial Pile Load Test: Garca River Bridge - Brazil
Paul George Alexander C.
The Bi- Directional Load Test provides us with the Unique ability to determine both the skin friction and the end bearing capacity of a bored pile at a single test simultaneously. To understand this methodology and the advantages of this pile load test a case study was conducted on an of shore pile across the River Garcia in Brazil. Where the pile was 1.4 m in Día, 20m in depth and had a working load of 8000kN. The methodology included the installation of load cells in the reinforcement at the fabrication stage which was completed in one single day and the test which was conducted at the end of 28 days. The testing was done to the twice of the piles working loaded which was exactly 16632kN. The results gathered at both the skin friction and end bearing was recorded and found satisfactory. The installation of the load cells and the entire testing process was conducted in less than 48 hrs. This test’s methodology is different to the conventional load test as there is no limit to the load that can be applied to the pile. This paper submitted with the intention that the paper will help us develop a better understanding of the methodology of the Bi- Directional load test, advantages and limitations, feasibility, interpretation of the results in hope that this will be a valuable addition to our esteemed field of deep foundations.
