摘要

TDR（時域反射儀）應用於大地工程之量測為一較新的發展，它除了可以量測與土壤基本物理性質息息相關之土壤電學性質，也可應用於地下水位監測及土壤、岩石之變形監測。本文將介紹TDR之基本量測原理，並詳細說明TDR在大地工程量測之使用方法；此外，對其未來之可能潛力與發展方向，也作了概略性的說明。

Application of Time Domain Reflectometer (TDR) in geotechnical measurements is a relatively new development. It can be used to measure electrical properties of soils that are related to soil physical properties. In addition, TDR has found applications in monitoring ground water level and relative deformation in soil, rock, or structure. This paper introduces the basic principle of TDR measurements and explains the methodologies of TDR measurements in geotechnical application. The potential and future development of TDR is also discussed.
