Description
Summary:Static load tests are considered the most reliable method to assess individual pile performance in the realm of foundation engineering. For the last few decades, an innovative method for testing the bored pile capacity by means of the Bidirectional Static Load Test (BDSLT), a self-balanced test, has been proved advantageous over the routine axial load testing method in many aspects. The load applied through the specially designed sacrificial jack makes it possible to measure simultaneously the displacement of upper and lower sections of the foundation element, enabling the separation and accurate measurement of the shaft and tip resistances. Even though the traditional top-down test has several disadvantages including longer preparation time and reaction system influences, many researchers and practicing engineers have been still concerned about the BDSLT method. This paper discusses the successful application of bi-directional static load testing in different projects in the Middle East to give assurance to use in future infrastructure projects.
