针对时域反射法(TDR)在边坡工程监测中的应用,在简要阐述TDR技术基本原理的基础上,通过对几种不同型号同轴电缆进行室内剪切试验和在实际工程的施工过程监测系统中进行应用试验,研究了不同型号同轴电缆在相同剪切变形条件下TDR波形的不同反映,对比分析了TDR技术与钻孔测斜技术的监测结果,得出了TDR技术能快速、经济、安全、准确确定边坡滑动面位置的结论,并提出了应根据监测目的选择不同型号同轴电缆的应用准则。研究表明,TDR技术非常适用于边坡勘察。
To apply the time domain reflectometry (TDR) to slope monitoring, on the base of brief summary of principle of TDR, and with types of indoor shear tests and situ construction of different cables, reflection waves of types of different cables are studied. Compared with the monitor results by TDR and oblique monitoring result by drilling hole, the follwing conclusions can be drawn, i.e. TDR can be fast applied to determining the sliding plane, economically, safely, and precisely. By the research results, to satisfy different monitoring goal, the application rules of types of TDR are put forward; and TDR is a very useful tool for slope survey.
