This paper analyzes the groundwater discharging course using fluidics theory and combining quay structure construction ; sets up the method of fast drainage by the dint of pipeline and blind ditch of fragment stone ; and gives the computational mathematical model for quay drainage and calculation formula for drainage process according to the principle of conservation of mass and underground percolation , which have been applied for quay ' s stability design and calculation 應用流體力學理論結合碼頭結構建設,分析了地下水排泄過程,借助管道和碎塊石盲溝建立了港口碼頭快速排水與擋墻基床排水的方法;運用質量守恒定律和地下水滲流原理,建立了港口碼頭排水計算數學模型和排水過程計算公式,并用在了碼頭的穩定設計計算中。
