时间域反射法用于滑坡监测的试验研究

Abstract

Abstract: According to the case of monitoring landslide, brings up the field method about the use of Time Domain Reflectometry (TDR) for monitoring landslide. In order to find out about the change rule of the cable fault, the test was carried on. On the basis of carrying on simulated test in the lab, an example of monitoring landslide was given based on TDR. Through to the analysis of the simulation test in the lab and the test data in the field, the authors discussed TDR monitoring landslide practical application effect and validity. The research material indicated that the landslide monitor technical method based on TDR is quite novel, compares with the traditional landslide monitor method. It has many characteristics such as saving the time, the cost inexpensively, the localization being accurate and so on. As a result, the TDR used for monitoring landslide, can fast realize, real-time, the continuous monitoring.

Key words: time domain reflectometry（TDR）, geologic hazard, landslide, landslide monitor
