摘要:
为探究混凝土受剪损伤破坏过程的声发射特性,开展了Z形试件的直剪和压剪破坏试验,联合累积能量、幅值和计数时变曲线、计数-幅值、上升角(RA)-平均频率(AF)及b值等多种声发射参数分析方法,探明了混凝土受剪损伤破坏过程的声发射特性。研究结果表明:压剪试件因水平力约束,具有更高的承载力,材料内部损伤劣化程度更高,声发射信号更活跃; 在微裂纹萌生阶段,所有试件的声发射信号幅值集中在80 dB内,振铃计数低于200,而在剪切裂纹成型、扩展和宏观裂纹阶段,其声发射信号幅值高于80 dB,该特征与受力形式无关; 所有试件的剪切裂纹单元数均超过80%,明显大于拉伸裂纹单元总数,说明各试件产生的裂纹以剪切裂纹为主,且其聚类中心的AF和RA范围分别为20～40 kHz和0.3～0.6 s/V; 竖向加载时,压剪试件的b值呈三阶段破坏特征,初始阶段b值较高且声发射信号幅值低于70 dB,损伤稳定扩展阶段b值数据点变得密集,且维持在1.4上下波动变化,而直剪试件此特征不明显,破坏阶段b值持续震荡下降,且80 dB以上高幅值信号剧烈增多,此外,b值首次持续下降预示混凝土材料出现剪切裂纹。
Abstract:
To explore the acoustic emission characteristics of concrete during the process of shear damage and failure, direct shear and compression shear failure tests were conducted on Z-shaped specimens. A combination of various acoustic emission parameter analysis methods was employed, including variation curves of cumulative energy, amplitude and counts over time, count-amplitude, rise angle(RA)-average frequency(AF), and b-value analysis. The acoustic emission characteristics of concrete during shear damage and failure were elucidate. The research findings indicate that due to the horizontal force constraint, the compression shear specimens exhibit higher bearing capacities, greater internal damage and deterioration within the material, and more active acoustic emission signals. For all specimens, during the initiation stage of microcracks, the amplitudes of acoustic emission signals are concentrated within 80 dB and the counts are below 200. While during the formation, propagation, and macrocrack stages of shear cracks, the amplitudes exceed 80 dB, and this characteristic is independent of the loading type. The numbers of shear crack elements exceed 80% for all specimens, significantly greater than the total number of tensile crack elements, indicating that cracks produced in each specimen are mainly shear cracks. Moreover, the AF and RA at the clustering centers range between 20-40 kHz and 0.3-0.6 s/V, respectively. During vertical loading process, the b-value of compression shear specimens exhibit three-stage failure characteristics. In the initial stage, the b-value is high and the amplitude is below 70 dB. During the stable damage propagation stage, the b-value data points become dense and fluctuate around 1.4, while this feature is not prominent in the direct shear specimens. During the failure stage, the b-value continues to oscillate and decrease, and there is a significant increase in high-amplitude signals above 80 dB. Furthermore, the first continuous decrease in the b-value indicates the emergence of shear cracks in the concrete material. 10 figs, 32 refs.
