摘要:

为了判断灌浆套筒内部是否存在缺陷,基于压电陶瓷检测方法,检测了不同缺陷程度的竖直向套筒和水平向套筒,比较了截面灌浆量对响应信号幅值的影响; 从小波包能量的角度分析了截面灌浆量对信号能量的影响,并基于小波包能量分析提出了缺陷评价指标; 通过有限元方法,模拟了应力波在不同截面灌浆量的灌浆套筒内的传播,分析了缺陷大小对应力波传播的影响。结果表明:响应信号幅值随灌浆套筒内部缺陷严重程度增大而增大,完全脱空情况下的幅值均值为灌浆饱满时的293%; 通过小波包能量分析,响应信号属于低频信号,基于小波包能量分析提出的缺陷评价指标能够定量反映灌浆套筒内部缺陷程度; 有限元模拟结果可视化地展示了应力波在套筒内的传播路径,内部缺陷的严重程度会对应力波的传播路径和能量耗散程度造成影响,灌浆量越小,内部缺陷越大,应力波传播越集中,最终能量损失越小。

Abstract:

In order to judge the defects in the grouting sleeve, based on the piezoelectric ceramic detection method, the vertical sleeves and horizontal sleeves with different defect degrees were detected, and the effect of different cross-sectional grouting volume on the amplitude of the response signal was compared. The influence of cross-sectional grouting volume on the signal energy from the perspective of wavelet packet energy was analyzed. Based on the wavelet packet energy analysis, the defect evaluation index was proposed. Through the finite element method, the stress wave propagation in the grouting sleeve with different cross-sectional grouting volumes was simulated, and the influence of the defect size on the stress wave propagation was analyzed. The results show that the amplitude of the response signal increases with the severity of the internal defects of the grouting sleeve, and the average value of the amplitude in the case of complete voiding is 293% of that when the grouting is full. Through wavelet packet energy analysis, the response signal is a low-frequency signal. The defect evaluation index proposed based on wavelet packet energy analysis can quantitatively reflect the degree of internal defects in the grouting sleeve. The finite element simulation results visually show the propagation path of stress waves in the sleeve, and the severity of internal defects will affect the propagation path of the stress wave and the degree of energy dissipation. The smaller the amount of grouting, the larger the internal defects, and the more concentrated the stress wave propagation, and the smaller the final energy loss.
