摘　　要：针对在高应变检测中经常出现的力信号偏心问题,在结果分析中通常是通过平均两个力信号抵消偏心的影响,但若偏心过大或信号失真,仍会对测试效果和分析结果造成明显影响。对钢管桩高应变检测中锤击偏心产生的原因进行具体分析,提出现场相应的处理建议,即根据锤击偏心产生的根源和对检测结果的影响程度,有针对性地调整传感器安装位置、微调桩架等。In response to the problem of eccentricity of force signals that often occurs in high strain dynamic testing,the effect of eccentricity can be partially eliminated by averaging the two force signals in results analysis.However,if the deviation is too large or the signal distortion,it will still significantly affect the test and analysis results.We analyze causes of the eccentricity of hammering in the high strain detection of steel pipe pile,and put forward the corresponding on-site treatment suggestions,such as the targeted adjustment of the installation position of the sensor and the fine-adjusting of the pile frame according causes of the eccentricity of hammering and its influence on test results.
