摘　　要：嵌岩桩的承载特性尚未被全面认识,无法准确估计桩基承载力会给工程带来的隐患或造成的浪费。高质量的泥浆是嵌岩灌注桩的技术关键,桩岩界面粗糙度和成孔时间则是影响侧摩阻力的重要因素,对不同岩石强度下应采取相应的施工方法。Bearing capacity characteristics of rock-embedded pile has not thoroughly been known,thus tech-nical risk and potential waste brought about by it can hardly be accurately assessed.In addition to the rough-ness of pile-rock touching surface and boring time,high quality slurry is also a key factor of rock-embedded piling technique.Differed construction method should be adopted to rock of different strength.
