摘要: 近年來單階自由跌水消能工已被廣泛運用在水利工程構造物中,其水舌衝擊力最大及最具沖刷潛勢,亦是消能工最易受損之處。本計畫擬以不干擾流場下量測自由跌水下游之壓力分佈數據資料,藉由應用類神經網路之倒傳遞網路模式倒傳遞類神經網路(Back-Propagation Neural Network, BPN),預測試驗所得水流特性參數,並藉渠槽試驗資料點作驗證,以評估其精確性。為使設計者更為便捷及設計後圖示之展示快速,將進一步建構自由跌水消能工設計之視窗化。
In recent years, free overfalls or vertical drops have been widely used in both naturaland artificial channels. According to previous experimental studies on free overfalls, nappeflow impact position and its striking force to channel bed are the main influential factors ofa drop structure. This experiment is set up to measure the pressure distribution along thedownstream flow of a free overfall and experimental data will be trained and validated bythe Back-Propagation Neural Network (BPN). Furthermore, windows-based programs willbe established for free overfall design. Thus, instant designing information can be acquiredin a short time.
