Description
Summary:碩士 === 國立屏東科技大學 === 水土保持系所 === 103 === The research has adopted time domain reflectometry technicality to monitor the landslide area in Tengchih Forest Road. A Time domain reflectometer was adopted to measure the degree of landslide. Great effects were obtained from the research. Aside from the setting cost at the beginning of the research, not much additional cost was spent. Therefore, it is more advantageous to adopt this device than the traditional inclinometer. Since the traditional inclinometer could not measure accurately if the layers slide too much, time-domain reflectometer had provided another option to monitor the degree of landslide in the modern world. Another experiment is conducted to analyze how wave shapes change as different lines produce deflection angles around the coaxial cable. The test result revealed that there is a high correlation between the deflection angle and the area generated from wave shape. As the angle approaches zero degree, the area below the wave shape increases and it has a high correlation with the height through statistical analysis.There is also a very high correlation between the angle and the height of the wave crest. As the angle approaches zero degree, the wave amplitude grows larger.There is also has a high correlation with the height according to statistical analysis.The thicker the lines and the smaller the intersection angle,the larger the area and the height of wave shape(reflection coefficient).
