本文在分析单桩的承载能力取决于桩身条件、桩周岩土介质的力学参数和受载的作用时间的基础上,探讨了单桩的动力和静力的承载机制。提出一种考虑桩周岩土介质动、静力学强度指标和加载速率的动测法,用它来确定摩擦桩的极限承载力。动测与静压试桩对比和工程应用表明,该法简便有效。
In this paper, based on the analysis of the bearing capacity of a single pile depends on the conditions of the pile body, the mechanical parameters of the rock and soil medium around the pile and the loading time, the dynamic and static bearing mechanisms of the single pile are discussed. A dynamic measurement method considering the dynamic and static strength indexes and loading rates of the rock and soil medium around the pile is proposed and used to determine the ultimate bearing capacity of the friction pile. The comparison between dynamic test and static pressure test piles and engineering application shows that this method is simple and effective.
