摘要

锚杆用于将输电塔的拉索固定在土中。因此，锚杆被埋入或包裹在地下的混凝土中，从而形成可靠的支撑体系。然而，在施工过程中经常出现锚杆注浆不全或不完善的情况，这可能导致锚杆失效，导致工程事故。因此，这种锚需要定期维护。频域反射法用于定位和量化混凝土锚杆可能出现的劣化。实验结果表明，反射法可能是一米锚杆无创维修的一种新方法。

A Non-destructive Inspection of Anchor Rods based on Frequency Domain Reflectometry

Anchor rods are used to fix the guy cables of transmission towers into the soil. Thus, anchor rods are buried or encapsulated in concrete beneath the ground, thereby forming a reliable support system. However, incomplete or imperfect anchor grouting often occurs during construction, which may cause the anchor to become ineffective and lead to engineering accidents. Therefore, such anchors require periodic maintenance. Frequency domain reflectometry is used to locate and quantize possible deterioration on the concrete anchors. Experimental results have shown that the reflectometry approach may be a new method for the noninvasive maintenance of anchor rods measuring one meter.
