高速公路锚杆锚固质量无损检测技术研究

Research on anchor bar quality nondestructive testing technique on highway

采用 LX 岩土工程质量检测分析仪，应用声频应力波法，对高速公路路堑边坡锚杆进行无损检测，这对各类锚杆的锚固质量检测和分级是可行和有效的．由于在公路系统锚杆锚固工程锚杆无损检测属首次应用，一些锚杆的锚固体系的无损检测条件不太理想．今后，随着应用的增多，锚杆的设计和施工进一步接近无损检测条件，相信声频应力波法对锚杆锚固质量的无损检测及高速公路的建设会提供更好的质量保障．

It is feasible and effective to inspect and classify the quality of anchor reinforcement on the slopes of high-way road by the method of stress wave and with LX inspecting apparatus.The geotechnical engineering can remainwithout damage.Because of the lack of experiences,the no-damage inspecting conditions of some anchors are not ide-al.With the increase of anchor application in highway construction,the inspecting condition will be getting better,sothe no-damage anchor inspecting method with stress wave of sound frequency will provide reliable support for thequality of anchor reinforcement to the slopes of highway road.
