高应变动测确定桩承载力大小误差力学分析

MECHANICAL ERROR ANALYSIS OF PILE BEARING CAPACITY OBTAINED FROM HIGH-STRAIN DYNAMIC TESTING

本文分析了桩基检测中高应变动测技术的理论基础中影响确定桩承载力大小的几个因素，对建立数学模型中桩侧和桩端动阻力与桩的实际承载力大小之间关系进行研究，提出此方法在确定桩的承载力大小过程中的不合理性及误差来源．

In this paper,many factors to determine load capacity of piles by high-strain method for pile test are analyzed.And the relations between dynamic wall friction or toe resistance and actual load capacity of pile inmathematical model are also studied.The error sources of high-strain method in the processing to determine load capacity are pointed out herein.This study has a certain significance in the popularizing high-strain method to determine load capacity of pile.
