Abstract
For the application of Time Domain Reflectometry (TDR) technology in landslide monitoring, a new mountain landslide slip amount calculation model based on TDR technology is put forward. This article describes the basic principles of TDR landslide monitoring and the theory of electromagnetic pulse propagation in a coaxial cable. Deduced calculation model of landslides slippage, conducted a laboratory simulation tests landslides, and discussed the landslides slippage effect on TDR waveform, get and verify specific calculation model by the test. The results showed that, TDR reflected voltage with the landslide slip amount is increasing, the different deformation point of the reflective voltage with the shift to a linear relationship. The two errors between calculation model slip and the actual slip are not more than 2 mm.
