| Summary: | 碩士 === 南華大學 === 科技學院永續綠色科技碩士學位學程 === 107 === Hillslope usually collapses due to rainfall and groundwater seepage. This study uses the theoretical formula of slope failure derived from Hong (2017). Laboratory experiment, including the compaction test, the K value test of Darcy's law, and the compaction drainage triaxial test were executed to obtain the parameters in theoretical equation, which can calculate the critical groundwater level where the collapse occurs. The results of the study can be used to derive the relationship between the critical groundwater level and the slope height. When the slope is equal to the internal friction angle, the water-free depth will still produce slippage, and the slope angle with the same critical depth and slope height will be introduced to provide relevant practical design supervision and safety. This study can be applied in the environmental monitoring of landslide.
