摘　　要：为保证贵州地区的桩基建设质量,文章分析了较破碎岩体的特征和嵌岩桩的竖向承载力机制,从桩周土性质、桩径、岩石强度、沉降等方面出发,分析了嵌岩桩竖向承载力影响因素,并以建筑物的嵌岩桩(中风化泥灰岩为持力层)为研究对象,利用静载试验检测了其竖向极限承载力,研究成果可为类似嵌岩桩工程设计和检测提供理论依据。In order to ensure the quality of pile foundation construction in Guizhou area,this paper analyzes the characteristics of relatively broken rock mass and the vertical bearing capacity mechanism of rock-socketed piles.From the aspects of soil properties around the pile,pile diameter,rock strength and settlement,the infl uencing factors of vertical bearing capacity of rock-socketed piles are analyzed.Taking the rock-socketed piles of buildings(with medium weathered marl as the bearing layer)as the research object,the vertical ultimate bearing capacity is tested by static load test.The research results can provide theoretical basis for the design and detection of similar rock-socketed pile engineering.
