Abstract:	透地雷達用於構造物上之檢測已是相當普遍，國內、外亦有許多學者專家對透地雷達之原理及相關應用有多方面的研究，透地雷達對於隧道襯砌混凝土結構內之厚度、裂縫及空洞之調查及判定，亦漸受到矚目，因此本研究將以頻率1GHz透地雷達對廢棄之鐵路隧道襯砌混凝土進行檢測，以電磁波波傳理論為基礎，配合訊號處理技術進行隧道襯砌混凝土之厚度、裂縫及空洞之調查與判定，利用電磁波對於各介質其介電常數不同會有明顯變化之特性，分析電磁波反射訊號特徵及波傳現象之差異，並加以探討電磁波反射訊號能量大小、波形等變化，以期能將透地雷達完整應用於 At present, using GPR on testing of structures is a common method, and many researches have been conducted on this area. However, there is scanty research on the thickness, fractures, and voids of the concrete structure of tunnel lining. Therefore, this s
