Study on the applicability of TDR in the landslide deformation monitor

摘要：

The deformation monitoring of landslide has an important place in landslide research,geological hazard evaluation and its analysis and prevention.There are kinds of landslide monitoring technologies but all of them have inadequate and all of them have the cost and reliability problems in nature.Time Domain Reflect meter testing techniques,named TDR technology is a kind of new coax technology with its pulse signal transmission,which reflects the slide and deformation auto information of the landslide as its base to monitor the deformation and the dynamic information of the landslide.From the research of TDR test indoor,under the strain,the test can effectively reflect pulling and shearing deformation;from the research of TDR in situ,the deformation location of the landslide is counterpart to the deformation location of TDR test and the deformation value is comparable to the value from bored tilt miter.TDR has the characteristic of the exact located and its cost is low,which is more applicable to the traditional monitoring technology.From the research,TDR is applicability in landslide monitoring.
