摘要
文中分析了锚杆无损检测原理及锚杆锚固质量评价方法,结合工程实例,对锚杆进行抗拉承载力检测。结果表明,随着锚固质量等级的降低,锚杆抗拉承载力的合格率逐渐降低;锚固质量等级为Ⅲ级或Ⅳ级的锚杆,应重点抽取锚杆抗拉承载力检测。
In the article,the principle of non-destructive testing of anchor rods and the evaluation method of anchor rod anchoring quality are first analyzed.Finally,combined with engineering examples,the tensile bearing capacity of anchor rods is tested.The results show that as the anchoring quality level decreases,the qualification rate of anchor rod tensile bearing capacity gradually decreases.For anchor rods with anchoring quality levels of IIl or IV,the focus should be on selecting anchor rod tensile bearing capacity testing.
