Abstract

Abstract: In consideration of the interaction between pile alld rock．the internal forces of a whole pile were analyzed by u- sing plane elastic-plastic finite element method．Using traditional‘‘K” method，the inner forces of a pile was calculated con- sidering pile bottoMbearing conditions as fixation，hinge，and freedoMrespectively，and then comparison was made with the finite element method．The comparison results shoWthat the internal force result of traditional“K” method is close to the re- suit of FEA． Therefore，pile bottoMbearing condition should be fixation in the design of rock-socketed pile．

Key words: rock-socketed anti-slide pile, bearing conditions, finite element method

摘要： 考虑桩岩相互作用，采用平面弹塑性有限元方法对嵌岩抗滑桩进行内力分析。同时采用传统K值法，桩端支承条件分别按固定、铰支和自由考虑，计算m3种不同支承条件下的桩身内力，并分别与有限元法的内力汁算结果进行比较。分析结果表明：传统K值法采用桩端周定支承条件得到的桩身内力更接近有限冗分析结果，故嵌岩抗滑桩工程设计中，桩端支承条件应按固定端考虑
