摘　　要：随着锚杆锚固技术在工程中的广泛应用,因现场施工锚固质量检测手段原因造成的事故与经济损失也越来越多,因此锚固质量检测新理论和新技术的研究成为目前迫切需要解决的问题。从锚杆传统拉拔检测技术的破坏机制、影响因素和数值模拟研究3个方面对锚杆锚固质量检测技术研究现状进行全面的阐述。从室内试验及现场试验、数值方法、应力波反射法和信号的处理及智能评估等方面全面分析和总结了无损检测技术的研究和应用现状。最后从锚杆无损检测技术目前存在的问题出发,提出了多种检测手段相结合的新技术研究、多种影响因素叠加效应的研究、智能评价系统的构建等将是未来锚杆无损检测技术的发展方向。With the wide application of bolt anchorage technology in the engineering,more and more engineering accidents and economic losses caused by the detecting technique for anchoring quality occurs. So the research of new theory and technology for anchoring quality testing becomes the problem that urgently needs to solve. A comprehensive description for the research status of the bolt anchoring quality detection technology is made from three aspects＂,that is the research about the failure mechanism,influence factors and the numerical simulation of the traditional bolt drawing detection technology. The comprehensive analysis and summarization of the current research and application status of the nondestructive testing technology are given from the laboratory experiment and field test,numerical method,the stress wave reflection method,the signal processing technology to the intelligent evaluation. Finally,according to the present problems of the anchor nondestructive testing technology,proposing that a new technology that combine a variety of detection means,the superimposed effect research of influential factors and the construction of intelligent evaluation system will be the future development direction of anchor nondestructive testing technology.
