解釋
挖泥竣工高程-
In order to reduce the re - deposit volume of the dredged channel, the method must be based on decreasing the oncoming sediment, changing the mouth site, builting the sediment control dam and raising the reservoir level
為了最大限度地減小疏浚挖槽的回淤量，必須依靠控制上游來沙量、調整入水口門位置、加設防淤堤及提高庫水位等手段，而不能通過調整挖泥槽寬度、位置及數量等措施來達到目的。 -
3. the drop datum of largest water level in researched reaches increases relatively with length increase of dredging channel in definite condition of discharge and sediment and definite dredged sediment quantity or dredged morphology of transversal section
在一定的水沙條件和一定的挖沙量或一定挖河斷面條件下，隨挖河長度增加，研究西安理工大學工程碩士學位論文河段最大水位降落值相對越大。 -
14 barges and hoppers, if utilized for marine transportation of dredged materials, shall not be filled to a level which will cause overflow of material or polluted water during loading or transportation
用作海上運送挖掘物料的駁船及底卸式駁船，所裝載的物料不應過滿，以免物料或污水在裝載或運送期間溢出。 -
It shows that the water level in the definite reach is lower than that with same discharges before dredging river, the surface slope on upper reaches dredged is enlarged and deposition load on bed is reduced or eroded
主要表現在可以引起一定范圍河段內的水位較挖河前同流量下有所降低，開挖上遊河段水面比降增大，床面淤積量有所減少或發生沖刷。 -
But when the dredged length have increased to a certain value, the increment of water level drop datum decreased continuously with length increase of dredging channel. in other word, unit length increment tends to slowly. when dredging channel length is in a certain datum region, the effect of dredging sediment for deposition reduction is better relatively
但是，當長度增加到一定值以後，隨挖河長度的增加，水位跌落值增量不斷減小，即單位長度的增加量逐漸趨緩；當挖河長度取于某一值域內時，挖河的減淤效果才相對較佳。
