摘　　要：为实现对桥梁基桩承载力的检测,本研究引入高应变法,并对某桥梁建设项目中的基桩进行承载力检测。在明确了桥梁建设项目的基本概况后,选择重锤、荷载箱、基桩静载仪、基桩高应变承载力检测仪器等设备。利用高应变法,提出改进高应变法的桥梁基桩承载力检测方法。经过检测,发现该桥梁建设项目的承载力特征值均超过了设计承载力特征值。同时,通过检测得到的极限承载力数值结果将可作为该桥梁建设项目承载力验收的依据。To achieve the detection of the bearing capacity of bridge foundation piles,this study introduces the high strain method and tests the bearing capacity of foundation piles in a certain bridge construction project.After clarifying the basic overview of the bridge construction project,equipment such as heavy hammers,load boxes,pile static load instruments,and pile high strain bearing capacity testing instruments were selected.An improved method for detecting the bearing capacity of bridge foundation piles is proposed by using the high strain method.After testing,it was found that the bearing capacity characteristic values of the bridge construction project exceeded the design bearing capacity characteristic values.At the same time,the numerical results of the ultimate bearing capacity obtained through testing will serve as the basis for the acceptance of the bearing capacity of the bridge construction project.
