无损检测技术在边坡锚固工程质量验收中的应用

摘要

Anchor cable reinforcement technique is extensively applied in various fields of geotechnical reinforcement engineering, and compliance of the length of anchor cable and grouting fullness with design requirements is an important indicator to evaluate anchoring effect. At present, audio frequency stress wave nondestructive testing technology is primary nondestructive testing means for anchoring quality. In combination with detection test for quality of anchoring project of ( side) slope on Banba-Jiangdi section of Shantou-Kunming Expressway in territory of Guizhou, this paper expatiates application principle of stress wave in detection of anchoring project quality with anchoring cable to provide experience and reference for application of nondestructive testing technology in detection of anchoring quality of anchoring cable of (side) slope.%锚索加固技术广泛应用于岩土加固工程的各个领域,锚索的长度及灌浆饱满度是否达到设计要求是其评价锚固效果好坏的重要指标.目前,声频应力波无损检测技术是主要的锚固质量无损检测手段.结合汕昆高速公路贵州境内板坝至江底段边坡锚固工程质量检测试验,阐述应力波在锚索锚固工程质量检测中的应用原理,为无损检测技术应用于边坡锚索锚固质量检测提供经验和参考.
