| Summary: | 碩士 === 國立嘉義大學 === 土木與水資源工程學系研究所 === 100 === According to the proposed rainfall triggered shallow landslide probability model, the hysteresis effect on the assessment of landslide probability is conducted in this study. Through several scenarios with various statistical properties of soil parameters and different slope conditions and hydrological conditions, the hysteresis effect on landslide probability due to groundwater table rise and matric suction dissipation is examined using the main drying curve and the main wetting curve. The simulated results show that landslide probability can be indeed influenced by the hysteresis effect. For the scenarios of groundwater table rise and matric suction dissipation, the landslide probability could respectively be underestimated and overestimated by using the main wetting curve as compared with the commonly used main drying curve
