中文摘要 | 本研究選定苗栗大湖鄉南湖溪中尺寸集水區為主要研究區位,利用TRIGRS 程式模擬降雨 入滲並分析坡地安全性。以敏督利颱風雨量及不同解析度之數值高程地形(DEM)模擬不同參數 因子變化下之坡地安全性,配合既有的調查資料作比較,驗證程式模擬結果的情形,藉此在有 限的野外調查資料下,估算合理化資料、參數,瞭解各影響參數因子與坡地穩定性之對應性。 |
英文摘要 | This research chooses the medium size watershed, Nan-hu Creek watershed in the Miao-li Hsan, as the study area. TRIGRS program is applied to simulate rainfall, infiltration and analyze stability. Using the rainfall records of Typhoon Mindulle and digital elevation models (DEM) of various resolutions, parametric study for the influencing factors is performed. Compared with a few investigation data, the outcomes of simulation are evaluated. Under limited field records, reasonable parameters and information are estimated to understand the correlation of the influencing factors and slopeland safety. |
