作为《建筑桩基技术规范》专题研究之一,本文对所收集的大量干作业法钻孔桩静力试桩资料进行了统计、分析,并阐述了确定单桩竖向承载力设计参数的方法。经过三次试算对试算参数进行了适当的修正,最后给出适合于干作业法钻孔桩设计的竖向承载力参数。 As one of the special studies on “Technical Specifications for Building Pile Foundations”, this paper analyzes and analyzes the data collected from a large number of static test bored pile static test piles, and elaborates the method for determining the design parameters of the vertical bearing capacity of a single pile. . After three trial calculations, the trial parameters were properly modified. Finally, the vertical bearing capacity parameters suitable for the design of dry working bored piles were given.
