On the basis of axial static load test data measured on 70 rock-socketed piles in 19 projects. thecharacteristics of the test results are described. The zoning is performed for P-S curve, the tab.le of qualityclassification system for the rock-socketed piles is presented, and the feature of deformation and failure forthese piles is studied. The types of failure are established and, in the meanwhile, the measurement of socketdepth and- the friction of the socket part of pile are discussed.
