锚杆锚固质量检测方法及应用

对锚杆锚固质量的检测一直为工程界所关注，本文比较了拉拔试验与声波反射检测锚杆锚固质量的方法，介绍了两种方法的基本原理以及相关的技术规定。鉴于拉拔试验方法上的不足，详细阐明了声波检测方法及其基本原理，并列举了应用于某高速公路隧道工程检测锚杆锚固质量检测的例子。

Detection of Bolt Bonding Quality and Its Application

Detection of bolt bonding quality is paid attention to in engineering field.In this paper,the comparison of the methods between acoustic reflection and pull-off test is made,and fundamental principle and related technical stipulation of these methods are introduced.In view of the limitations of the pull-off test method,fundamental principle and method for acoustic reflection are discussed in detail,and an example that has been used in the tunnel construction of an expressway is given.
