| 中文摘要 | 近年來各項工程水理相關設計除安全考量外,亦應儘量符合自然生態工法之需求。採用較合理且簡便的水理演算模式,可有效地進行河道斷面及工程佈置之設計規劃。美國工兵團之HEC-RAS模式,考慮實際河道斷面幾何特性及糙度,且可考量水工結構物(如橋墩、橋台、涵洞等)造成之束縮突擴效應,具備較完善之水理計算能力。本研究採用HEC-RAS模式,針對台北縣雙溪鄉丁子蘭坑溪之第一至三期整治河段進行水理計算;同時進行水工模型試驗,試驗成果與水理演算模式模擬結果相互比較分析,並獲得良好之比較成果;由成果可說明HEC-RAS模式可作爲野溪水理計算之良好工具。 |
| 英文摘要 | Except safety consideration, hydraulic design should satisfy the demands in the ecological point of the view. Taking a robust and user-friendly hydraulic computational model can speed up effectively the hydraulic engineering design and layout. The HEC-RAS model was developed by the Hydrologic Engineering Center of the U.S. Army Corps of Engineers. This software allows the user to perform one-dimensional hydraulic computation based on various geometric characteristics, roughness of river sections and contraction/expansion effects of hydraulic structures in a river. The Tin-Chi-Lan-Kan Creek located in the Taipei County is selected as a study site. An experimental study is also conducted by constructing the physical model for this site. The measured water levels are compared with the calculated results by HEC-RAS model. The applications of HEC-RAS model in the Tin-Chi-Lan-Kan Creek demonstrate the effective potential in the upper land streams. |
