Résumé / Abstract

The design of bored piles in residual soil is usually based on empirical correlation with the results of the standard penetration test, regardless of the construction method of the bored pile. This paper presents the pile load test results of two bored piles with different construction methods. A preliminary bored pile of 1000 mm diameter was constructed using a wet method with bentonite as the stabilising fluid. The static pile load test result shows that the shaft friction could be overestimated by the empirical method. A 1200 mm diameter bored pile was constructed about 5 m away from the preliminary bored pile but using the dry method. The static pile load test result shows that higher shaft friction can be obtained. The empirical method could underestimate the shaft friction in this case.
