摘要:锚杆锚固技术作为各类地下工程及边坡护理的主要手段,已在交通和水电站建设等工程施工中得到广泛应用,其锚固质量和运行状况的无损检测已被提到议事日程。声波检测技术是目前主要的锚杆锚固质量无损检测手段,本文通过对我国锚杆锚固质量声波检测技术的历史回顾和现状分析,指出其理论研究工作的严重欠缺是当前存在的主要问题。文中还强调了模型实验研究的重要性,并指出理论研究应与模型实验紧密结合,二者不能偏颇。

Abstract: As the primary technique to offer safety and productivity improvements to underground projects, rock bolts have been widely used in the construction of traffic projects and water and electricity stations. The quality of the rock bolts are of great importance and have been paid a lot of attention. Sonic wave techniques are currently the leading methods used for evaluating the condition of rock bolts. This paper reviewed the history of some sonic wave techniques used for the inspection of rock bolts in China and analyzed their theory and application situations. It is pointed out that the theoretical problem is the primary problem existed in theses techniques. It is also emphasized that laboratory specimens are as important as the theoretical researches in studying these techniques.
Key words: Rock Bolts; Non-destructive Testing; Sonic Wave Method
