綠色公路逕流抑制設施功能評估

Assessing the Runoff Control Performance of Green Road

指導教授 : 林鎮洋

摘要


本文論述台中生活圈2號線環中路高架橋工程,該工程運用低衝擊性開發技術,將高架橋面上中央分隔島雨水導入雨水貯集系統,經過濾設施後噴灌橋面中央分隔島植栽;雨水過多時,則溢流至入滲池及入滲溝後流至地表下。藉由生態工程之儲存、滲透、蒸發及保留等方式,使暴雨獲得最好管理與回收再利用,期能落實節能減碳政策與營造生態城市。 依據台中地區近10年(2004年∼2013年)氣象資料顯示,豐水年為2005年(2,574.5mm),枯水年為2011年(1,204.9mm),故本研究蒐集2005年及2011年氣象資料,利用SWMM模式,模擬本綠色道路所建置之LID設施的地表逕流削減效益。結果顯示設置LID設施後,豐水年(2005)逕流抑制功能達43.5%,枯水年(2011)更達54.5%。而豐水年的個別設施以入滲池49.4%最佳,其次為入滲溝27.0%、雨水貯集系統3.8%、生態池1.9%;枯水年的入滲池70.3%最佳、入滲溝41.2%、雨水貯集系統7.9%及生態池3.8%。本研究亦利用SI值(Sensitivity Index)判別SWMM模式中使用之LID設施參數敏感度,結果以LID設施內部土壤滲透率參數最為敏感。

The thesis addresses the Huanjhong Road elevated bridge project of the Life Circle No. 2 highway in Taichung City. The project incorporated low impact development (LID) practices by directing runoff from the road’s central dividing island into a rain barrels. After filtering, the runoff water is used to irrigate vegetation planted on the island. During large storm events, excessive runoff would spill onto an infiltration pond and an infiltration trench and into the underground. Through the use of these eco-friendly practices, which store, infiltration, evaporate and conserve runoff for recycling and reuse, it is hoped that the government’s low-carbon policy and eco-city expectations can be fulfilled. According to the recent 10-yea (2004-2013) weather records for Taichung, 2005 was a wet year (2,575 mml) and 2011 was a dry year (1,205 mm). Therefore, we collected detailed weather data for the years of 2005 and 2011, and used the SWMM model to simulate the runoff reduction efficiencies of the LID practices installed at the green road site. The results show that, after LID installations, the practices collectively caused a runoff reduction rate of 43.5% for the wet year (2005) and 54.5% for the dry year (2011). As for the individual LID practice performance, for the wet year (2005), the infiltration pond was the best at 49.4%, followed by the infiltration trench at 27.0%, the rain barrels at 3.8%, and the eco-pond at 1.9%. For the dry year (2011), the infiltration pond was again the best at 70.3%, followed by the infiltration trench at 41.2%, the rain barrels at 7.9%, and the eco-pond at 3.8%. In addition, a sensitivity analysis was made using the SI (sensitivity index) value to determine the sensitivity of the various LID practice design parameters in the SWMM model. The results show that the hydraulic conductivity parameter of the soil media in the LID practices was the most sensitive one.
