大漢溪上游段攔河堰水工模型試驗

Model Study of Proposed Dashi Weir and Wulin weir in Dahanshi River

指導教授 : 許中杰

摘要


本研究應用水工模型試探討大漢溪上游段於大溪橋與武嶺橋段築堰前、後之水理變化及尾水流況,並建議適當之堰址與堰頂高程。試驗成果將與一維性水理數值模式之模擬結果比較。 試驗結果顯示大溪堰堰址應位於大溪橋下游110m處,而堰頂高程為EL.=80.5m。另外,試驗結果顯示一維性水理數值模式之模擬結果與試驗結果相當吻合。

This study conducted a model test for the flow in the Dahanshi river after building the proposed Dashi weir and Wulin weir. The test results were also used for the verification of the simulation results of one-dimensional numerical model. The test results show that Dashi weir should be located at 110m downstream of the Dashi bridge and the weir elevation is EL.=80.5m. Also, the test results and the one-dimensional numerical results are in good agreements.
