中文摘要

關於隔離牆設計規劃，本研究以施瓦茲克里斯托夫轉換理論計算流場，選取兩道水流中間的流線近似為隔離牆設計位置，藉此發揮導流作用。為貼近真實流況採用包含黏滯效應的深度平均淺水流模式，計算隔離牆牆體受壓情形，檢視隔離牆位置是否恰當。本研究採用台灣中港大排與貴子坑溪隔離牆作為分析案例，研究發現現有隔離牆僅於特定流量比例時方能發揮最好的導流效果，為避免隔離牆於其他流場中產生壓力不平衡之問題，本研究亦對既有隔離牆提出改善辦法。以多孔介質材料建造隔離牆得以有效舒緩牆體兩側壓力差，降低結構受損之可能，對未來河川治理工程將有所幫助。
英文摘要

About the design of dividing wall, this study selects the approximate line between two streamflow line as the dividing wall position based on the Schwarz-Christoffel transformation method. To correspond the real flow condition, this study applies the shallow water flow of depth averaging with viscous effect mode to calculate the pressure condition between fluid and wall for confirming the appropriate location of dividing wall The research will discuss the case of confluence between Zhonggang chnnel and Quizikeng river as well as find the best diversion effect when using the specific flow ratio. Furthermore, the study successfully proposes an approach to improve present dividing wall by using porous material with the property of dissipating pressure.
