摘要

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。

Abstract

Based on the fact that the bearing capacity of pile depends of the condition of pile body

mechanical parameters of the media around it

and loading period

the mechanism of dynamic and static bearing capacity for the single-pile is studied. Considering loading rate and difference between dynamic and static mechanical strengths of rock and soil media

a dynamic measurement is proposed to determine critical bearing capacity of frictional piles

which has been proved to be simple and effective with engineering applications and comparison between dynamic and static tests.
