River Regulation of a Phosphate Mine Area in the Three Gorges Reservoir Area
In order to meet the requirements for flood prevention, the blocked river channel of a certain phosphate mine area which located in the Three Gorges Reservoir area requires to be regulated. The river channel has the features of mountain-rivers. The flood prevention standard of the river channel is designed to prevent 50-year flood according to the local meteorological and hydrological data. The gravity gabion retaining walls has been used to support side slopes, the Reynolds gabion cushion has been used to protect the bottom, and the reinforced Mack mattresses has been employed to protect slopes. The results indicate that the minimum cross sectional area of the river is 25.743 m2 under the condition of 50-year flood, which is lower than the designed maximum cross sectional area of the river 31 m2, meaning that the design of the river channel meets the flood prevention requirements. In addition, the special material composition and structure features of gabion structures do not only overcome the defects of the traditional structure which features stereoplasm imperviousness and is prone to aging and failures, but also are characterized by good foundation adaptability and ecological features. This project can be referred to similar projects as the new ideas in river regulation of mine mountain areas.
