碩士 === 國立臺北科技大學 === 資源工程研究所 === 101 === The deep-seated slope movement is the one characterized by a huge scope moving mass with a deep sliding surface, low displacement rate, or a connecting of several moving masses with deep sliding surfaces. The existence how to affirm the deep-seated slope is an important project of domestic side slope disaster prevention and control with sliding range. A deep-seated slope movement case with many years monitoring data and 50 years of aerial photograph in southeast Taiwan, this article investigates the site characteristics of the slope. Borehole investigations, collecting monitoring and identification aerial photograph revealed the presence of unstably slope, which when integrated with inclinometer, image-mosaic technology detecting lining cracks and surface geodetic data, helped to provide key insights into the underlying instability mechanisms. Surface and borehole investigations of the unstable mass reveal an up to 90 m deep of metamorphic rocks divided into three primary blocks. The result showed deep-seated slope tended to move towards toe of slope and discontinuity attitude .The different response of microseismic measurement can make a distinction of slip the region and outside.
