A Method for Predicting Load-Settlement Relationship and Bearing Capacity of Single Piles by Means of CPT
Wang Huichang; Sichuan Institute of Building Research, China

A tentative method for predicting load-settlement relationship and bearing capacity of single piles based directly on the results measured by cone penetrometer with local friction sleeve is presented. It is possible that the load-settlement curves can be constructed by means of CPT and the problem of both the bearing capacity and the settlement behavior of single piles can be considered jointly. The proposed load-transfer functions are continuous, positive monotonic and nonlinear. A concept of weight mean point resistance 2D above and 4D underneath the pile base to determine the unit ultimate base resistance of piles is presented. The predicted results of seven jacked piles in loess are in good agreement with the load test data.
