Summary: | 碩士 === 華梵大學 === 環境與防災設計學系碩士班 === 98 === Taiwan is an island with limited flat lands. Therefore, development of slopes is inevitable. Huafan University is located on Ta-Lun Mountain at an elevation of 550m. This research discusses the judgment of monitoring results and the countermeasures for the dip slope case of Huafan University. In general, for the safety use of a slope land, in addition to the survey, planning and design before development, it is equally important to have slope monitoring system and constant monitoring. This helps to understand the status of the slope and analyze its stability. Also, a monitoring plan can be established to prevent disasters from happening, protect every one living in campus from life-threatening risks and facilitate the sustainability of the slope.
The monitoring data of Huafan University showed that there is a distinct trend of long-term displacement in various parts of campus. Judging by the results from slope-indicator showing displacement depth and rate, beside, by way of surface cracks observation and several geological surveys, there are 6 major potential sliding surfaces exist in the slope of the campus. Moreover, comparing the activeness of sliding masses from the slope-indicator displacement rates, 3 of the 6 sliding masses are more active than the rest. By correlating the displacement data of slope-indicator and the data of typhoon rainfall and earthquake during monitoring period, it was found that there is a clear relationship between the cause of campus displacement and the abundant rainfall that came with typhoons. Thus, the study intended to find out the direction of groundwater flow and groundwater reservoirs, and investigate the more active sliding masses and control of groundwater in the campus. The finding was compared to the analysis results of STABL program, to verify the correctness of the sliding surface judgments. The result was provided for not only the integration of campus safety monitoring and stability analysis, but also for reference of monitoring, long-term stability analysis and operation maintenance of slope developments in the future.
