大直径钻孔灌注桩已成为高层建筑较常用的基础形式之一，但其理论研究远不能适应实际应用。根据浙江地区部分试桩资料对大直径钻孔嵌岩灌注桩的承载特性进行分析，并与有关分析结果进行比较，为合理利用该桩型提供一定的理论依据。 Large diameter cast-in-place bored piles have become one of the most commonly used basic forms of high-rise buildings, but their theoretical research is far from adapting to practical applications. According to the data of some test piles in Zhejiang area, the bearing characteristics of large-diameter drilled rock-socketed piles were analyzed and compared with the analysis results, which provided a certain theoretical basis for the rational use of the pile type.
