| Popis: | Pile foundation is one of the most commonly used types of deep foundations provided when the required bearing capacity of the soil is not achieved through shallow foundations. Comparatively, the pile foundation is more complex to design and has a greater impact on the economy of a project. The unpredictable and heterogeneous nature of soil demands to verify analytical pile capacity by performing a full-scale pile load test. Different methods with unique assumptions and limitations are available to interpret ultimate pile capacity based on the results of the pile load test. This study provides a quantitative analysis of eight commonly used methods and investigates the most suitable and reliable interpretation method to be adopted for cast in situ piles. A comparison between these pile capacity interpretation methods is made using a database of 45 pile load tests conducted on the cast in situ (bored) piles as per the procedure specified by ASTM-D1143. The consistency and accuracy of each method are quantified statistically using pile capacity predicted analytically and pile capacity interpreted based on load test results. Debeer intersection load and Mazurkiewicz methods were found to be the most suitable and reliable pile capacity interpretation methods for bored piles. |
