中文摘要 | 防砂埧之主要功能為攔阻砂石及穩定河床,惟其攔砂量之合理計算、埧高與間距之正確選擇,均有賴於埧體上游淤砂坡度之正確推估。防砂埧上游之淤砂坡度,淤滿之後仍然繼續變化,其大小、形態、以及達到穩定之時間,與當地之地文與水文條件有密切關係。據此,本文乃參照國內外現有之文獻,從靜態及動態平衡之基本觀念,探討淤砂坡度之變化形態與各 種模式之可靠性,同時列舉今後之研究方向或課題,以期能提出更合理、可靠之淤砂坡度推估模式,做為國內今後防砂埧規劃設計之參考依據。 |
英文摘要 | The major functions of sabo dam are sediment-trap and channel stabilization. But the rational estimation of sediment-trap, proper choice of the dam height and the dam spacing depend on the correct calculation on the upstream debris, slop of the sabo dam. This slope will continuously change even after the full-fill of the dam. The magnitude, type and required time to establish stability have relationship with the local conditions of physiography and hydrology. Hence, this paper in accordance with the domentic and foreign existing reports, studies the change, types of debris slope and the reliability of the various mathematical models from the concept of both static equilibrium and dynamic equilibrium. Futhermore, this paper enumerates the directions and themes of investigation in order to find the more rational, reliable debris slope estimating model which can be a reference for domestic sabo dam planning and design. |
