锚杆锚固质量弹性波检测技术研究现状
|
摘要
通过对锚杆锚固质量弹性波检测技术的历史回顾和现状分析,指出要解决好锚杆长度的精准检测问题,仅依靠对现有检测技术的改良是不可能的,该技术的突破方向可能需要结合声超构介质材料,设计新型高灵敏度的传感器,采用扩频技术中伪随机编码方式。关于砂浆饱满度的求取问题,现有的方法过于粗糙,应用理论亟待完善,应开展基于锚杆锚固体系条件下的数学模拟计算和室内物理模型实验研究工作,可以尝试研究锚杆杆底反射回波的频率与其砂浆饱满度的相关关系,建立两者之间的关系式,从而解决砂浆饱满度的求取这一问题。
This paper reviewed the history of some elastic wave techniques used for the inspection of rock bolts and pointed out that to solve the problem of precise detection of the length of the anchor rod, it is impossible to rely solely on the improvement of the existing detection technology. Its breakthrough direction may require the design of new high-sensitivity sensors combined with acoustic metamaterials, and use of pseudo-random coding methods in spread-spectrum techniques. With regard to the problem of obtaining the fullness of mortar, the existing methods are too rough and the application theory needs to be improved urgently. The next work is mathematical simulation calculation and indoor physical model experimental work under rock bolt anchoring system conditions. It is possible to try to study the correlation between the frequency of reflection waves at the bottom of the rock bolt and the mortar fullness, and establish the relationship between the two. In the end, some suggestions are preoposed for the main problems in the elastic wave detection technology of the rock bolt anchoring in China.
