本研究主要針對位於八德路建國南路口之建國及新生兩系統下水道間之連通結構物進行水工模型試驗。本試驗包括恆態定量流與非恆態定量流試驗。前期試驗結果提供台灣世曦工程顧問公司進行一維性數值模式(XP-SWMM 10.5)之率定。再應用率定後之一維性數值模式模擬而得之上、下游邊界條件進行試驗驗證一維性數值模式之精確性,試驗結果與模式模擬結果相當吻合。 This study conducted a steady and unsteady open-channel flow model test of the largest connecting structure between Jianguo and Xinsheng drainage systems in Taipei city. The preliminary test provided the one-dimensional numerical model, XP-SWMM 10.5, with depth-time relationships at manholes for calibration of the parameters. Then, by providing the upstream and downstream boundary conditions, the simulation results of XP-SWMM 10.5 and the results of model test were verified to be in good agreement.
