BEARING BEHAVIOR OF LARGE-DIAMETER ROCK-SOCKET PILES
大直径人工挖孔嵌岩桩的承载性状

Through simultaneous observation of pile-cap settlement,pile-end resistance and axial stress distribution in large-diameter rock-socket pile under multi-storied building construction,some new practical testing data are presented. Based on these data,the characteristics are analyzed of large-diameter rock-socket pile in working conditions,including pile cap settlement,distribution and exertion of pile-skin and pile-end resistance,selection of rock-socket depth,and the effect of pile end enlargement on pile-skin resistance and pile-end resistance.
