Determination of the bearing capacity of pile foundations based on CPT test results

The method implementing CPT results in order to determine pile's bearing capacity is presented. In this method, the shaft and base bearing capacities contribute to the determination of whole load-settlement curve making use of respectively chosen load-transfer function. The method has been developed on the basis of filed measurement of piles being applied to loading tests as well as CPT testing in the area of piling. Totally, tests for 94 Vibro and large bored piles installed under differentiated soil conditions were analyzed. The test results have been interpretated statistically by estimating the method parameters and by verification of various statistical hypotheses.
