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。
Based on the basic principle of Time Domain Reflectometry (TDR), the field work method of TDR in landslide monitoring is proposed. In order to better understand the changing rules of cables, indoor tests were conducted. Combined with the practical application, the field application example of TDR monitoring landslide is given. Through the analysis and comparison of indoor simulation test and field application test data, the practical application and effectiveness of TDR monitoring landslide are discussed. The results show that, compared with the traditional landslide monitoring methods, the technology of TDR for landslide monitoring is relatively new, which has the characteristics of saving time, low cost and accurate positioning. Thus, TDR is used for landslide monitoring, enabling fast, real-time, continuous monitoring.
