| 摘 要： | 依据时间域反射测试技术(TDR)的基本原理,提出了TDR技术在滑坡监测中的野外工作方法。为了更好地了解电缆的变化规律,进行了室内试验。结合实际应用,给出了TDR监测滑坡的野外应用实例。通过对室内模拟试验和野外应用试验数据的分析、对比,讨论了TDR监测滑坡的实际应用效果和有效性。研究结果表明,与传统的滑坡监测方法相比较,TDR用于滑坡监测的技术方法比较新颖,具有节省时间、成本低廉、定位准确等特点。由此可见,TDR用于滑坡监测,能够实现快速、实时、连续监测。

| 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. |
