中文摘要 | 深開挖工程抽水計畫的計算主要在於決定抽取率以及所需之井數,來維持開挖面以 下所降低之水位。本文提出抽水計畫之一般原則與實算步驟,並以高雄市一處深開挖工程為 例,探討深開挖基地之降水計畫。文中亦以有限元素法,針對案例分析階段性開挖下的降水 效果。本文結果指出,所提出之降水計畫原則與步驟,輔以有限元素法,可用於深開挖工程 之抽水計畫之研擬。 |
英文摘要 | The aims of the calculations for dewatering of excavations are to determine the required pump rate and the needed number of wells to lower the groundwater below the excavation level. This paper presents the principles and a procedure for the calculation of dewatering. A case study of a site in Kaohsiung City is presented as an example. The finite element method is adopted to perform the computational works. It is found that the presented procedure together with the finite element analysis can provide a useful way to make-up the dewatering plan of excavations. |
