锚杆无损检测技术在福建省边坡支护工程中的应用研究

本文基于应力波的传播理论以及反射法检测的原理,进行了锚杆模型试验,并结合福州大学阳光学院边坡工程实例,从锚杆的有效锚固长度、注浆密实度及缺陷大小和位置三个方面评价锚杆的施工质量,使得锚杆无损检测技术在福建省锚杆锚固质量评价中得到了初步的应用。同时本文对影响检测精度较大的因素做了简要分析,为下一步的研究提供了方向。

Study on Nondestructive Detection Technique of Bolt in Slope Reinforcement Engineering in Fujian

Basing on the principle of Stress wave’s transmission and reflection,this paper made a model test.And then it evaluated the quality of Anchor of Fuzhou Sunshine College Slope Reinforcement Engineering,from the effective anchorage length of the bolt grouting density and defect size and location.It making Anchor non-destructive testing technology has been a preliminary application in Fujian Province anchoring quality evaluation.This paper also made a brief analysis on the factors affecting the detection accuracy,providing a direction for future research.
