TESTING STUDY ON BEARING BEHAVIOURS AND FAILURE MODE OF ROCK-SOCKED PILE
嵌岩桩承载性状和破坏模式的试验研究

Based on the field loading test and the laboratory model test, the bearing behaviors and the failure mode of rock-socked pile foundation are discussed. The results of the analysis show that the rock-socked pile posses the loading behaviors of friction pile or end bearing pile, which is dependent on geological condition and design methods. The failure mode of rock-socked pile is related to the relative rigidity of pile and rock, and the failure may occur in (1) the interface of rock and pile, (2) the rock around the pile and (3) the pile itself.
