摘要

通过对不同位置预制裂缝的混凝土三点弯曲梁进行声发射试验

开展了不同预制裂缝偏移比下混凝土Ⅰ-Ⅱ复合型断裂的声发射过程参数、状态参数、统计参数分布规律

以及参数间相关性研究。结果表明:振铃计数—时间曲线、能量释放率—时间曲线的突变可表征Ⅰ-Ⅱ复合型断裂过程的临界状态

随着预制裂缝偏移比的增大

峰值荷载增大

试件脆断性增强;部分声发射过程参数间具有高度或中度相关性;随着裂缝偏移比的增大

试件起裂阶段主频均以低频占优

失稳阶段主频呈现"高—低"趋势。该研究可为混凝土损伤状态判别提供一定基础。

Abstract

Acoustic emission（AE）experiments were carried out for three-point bending beams with notch in different positions.The AE process parameters

state parameters

statistical parameters and the correlation between partial AE parameters were study for Ⅰ-Ⅱ mixed mode fracture process of concrete beams with notch in different positions.Results showed that the critical state of Ⅰ-Ⅱ mixed mode fracture process can be characterized by mutation information of the ringing counts-time curves and energy release rate-time curves.With the increase of notch offset ratio

maximum load increased gradually

and the characteristics of brittle fracture for specimen was obvious.There was high correlation or moderate correlation between partial AE process parameters.With the increase of notch offset ratio

the dominant frequency was low frequency at initial fracture moment

and the dominant frequency had a trend of"high-low"at the unstable fracture moment.This study can provide a basis for determining the damage state of concrete.
