摘　　要：通过对钻孔桩基岩覆盖岩增厚时的两种不同地质情况,从单桩轴向承载力、嵌岩深度两方面所作的对比计算说明:在微风化花岗岩上,其上覆弱风化花岗岩的岩层增厚时,可以减少微风化花岗岩的嵌岩深度,以利现场对桩基终孔控制和监理监控。Through to time the drill hole pile bedrock duplicate roof rock accumulation’s two different geological situation,from the single pile axial supporting capacity,inlays the contrast computation which the crag depth two aspects do to explain：When micro decency granite,above duplicate weak decency granite rock layer accumulation,may reduce the micro decency granite to inlay the crag depth,In order to help the scene to pile foundation finally hole control and overseeing monitoring.

关 键 词：嵌岩桩 覆盖岩增厚 终孔 单桩轴向受压承载力 嵌岩深度
