錯動變形監測在大地工程實務上扮演著相當重要之角色，無論是 在壩體底部錯動之監測、支撐開挖側向土體滑動之監測或堤岸及其它 建物之監測，均佔有重要之地位，尤其在邊坡穩定上，其重要性更不 可忽視。
隨著通信與電子科技之進步，錯動監測方法更不可停滯不前，必 須引進科技之進展，創新現有之方法。TDR 錯動變形量測系統便享 有科技之成果，與傳統儀器比較，不僅可連續性量測錯動變形剖面，
更可達成遠端即時監測之便利。但是在錯動變形量化上，至今仍無通 用之方式，以下就本研究試驗結果做進一步結論與建議。
5.1 結論
5.1.1 TDR
1.隨纜線長度之增加，線性迴歸出反射訊號初始值(initial response)
有增大之趨勢，為衰減與上升時間增加所造成，但是超過一定之 長度後又突然變小，為線性迴歸之斜率變緩而影響橫軸截距。
2.無論是使用 RG58AU 或 CommScope 同軸電纜當作延長線，在對
應相同之錯動位移量下，反射係數均隨著延長線之增長而變小。
3.相較於 CommScope 延長電纜，隨著 RG58AU 延長線增加，反射 訊號變的極不明顯，電阻R 會嚴重影響反射訊號之判識。
4.在錯動變形量化上，利用 R 之 TL model 模擬反算分析，可求得 錯動變形量與電纜阻抗有一致性之關係。
5.現地埋設錯動變形感測電纜，需選用低衰減性同軸電纜，延長線
與感測器為同一條，埋設前必須在試驗室做標定試驗找出阻抗與 錯動量之關係。
5.1.2 OTDR
1.以 OTDR 光纖量測錯動變形，能較早於 TDR 錯動變形量測系統 辨別出錯動發生之位置。
2.就光纖(a)之設置而言，錯動變形量與光損失呈現正相關。
3.與 TDR 錯動量測比較之下，OTDR 錯動量測靈敏度高於 TDR、
低衰減(相對於量測距離)、量測錯動變形範圍小，正好與 TDR 錯動量測形成互補效果。
5.2 建議
1.本試驗不考慮剪力帶寬度之影響，未來可進一步加入空氣區間或 灌漿材料剪力帶寬度、電纜－灌漿材料互制行為之相關研究。
2.OTDR 之光纖初始反應比 TDR 感測電纜佳，埋設現地時可先獲 知錯動發生位置，必須要注意的是光纖直徑小柔性高，現地埋設 較TDR 感測電纜來的困難。
3.由光纖(a)與(b)比對可知，若光纖附著於一緩衝材料上，部分變 形由緩衝材吸收，將可延伸其錯動變形量測範圍，緩衝材的選擇
必須軟硬適中，除可使光纖產生變形，亦可吸收部分變形，未來 可進一步做使用緩衝材之研究。
