摘要 根据19个工程71根嵌岩桩静载试验的实测资料,论述了嵌岩桩静载试验结果的特点,对P-S曲线进行了分区,提出了嵌岩桩质量分类体系表,研究了嵌岩桩的变形与破坏特点,并对破坏类型作了划分;同时,还讨论了嵌岩深度和嵌固力的测定。 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.
