Abstract
In modern construction, piles are often used due to their environmental friendliness and their ability to withstand large loads. However, different calculation methods are used in their design, which is suitable for specific geotechnical conditions. One of the main methods of ensuring the load-bearing capacity of piles is the static test of piles. However, when interpreting the results and the load-settlement curve, the problem arises of how to choose a method for determining the ultimate bearing capacity. This article reviews six graphical methods, applied to nine different length and diameter CFA piles installed in different construction sites in Lithuania. After analyzing the results, it was found that the largest variation of ultimate bearing capacity values was observed using the Decourt, Chin-Kondner, and Brinch Hansen 80% methods, while the smallest was observed using the Corps of Engineers method. It was also noted that when different load settlement curves were present, the Decourt, Chin-Kondner, and Brinch Hansen 80% methods yielded several times higher ultimate bearing capacities than those obtained using other methods.
