THE ANALYSIS OF RESULTS FROM ROUTINE PILE LOAD TESTS

This paper analyses the results from axial testing of vertical single piles showing that valuable information can be obtained from actual testing in the field. The author suggests that, because engineers are mainly only concerned with the pile having a certain least capacity, little is known of the actual capacity and the pile-soil interaction. The quick tests currently operated in the United States and Europe are reviewed. Often the definition of failure load as the condition where the pile plunges is inadequate. Nine failure criteria are compared and load-movement curves are given for each method. Reasons are given for prefering the Davisson limit load, the Chin failure load, the Brinch Hanson 80% criterion and the Butler and Hay failure load. An example is given of the influence of errors on the estimation of pile strength. Details are given of a quick test on a 40 M long 300 mm diameter precast concrete pile. Results show that a large amount of extra information can be gained simply at a low relative cost. (TRRL)
