黄河下游放淤改土固堤技术分析

Technical Analysis of Soil Amelioration and Dyke Strengthening by Warping in Lower Reaches of Yellow River

根据黄河下游滩区放淤改土固堤的实践 ,对淤临河洼地、淤滩改土、淤村塘洼地、淤串沟等放淤类型进行了分析 ,提出了放淤改土固堤进水口门、输水渠、围堤、退排水工程布置方法和引水量、放淤量的计算方法。

According to the practice of soil amelioration and dyke strengthening by warping in the lower reaches of the Yellow River, the following warping types are analyzed: warping the lowlands close by the river; soil amelioration by warping; warping the villages' pool and lowland; warping the guts, etc.. For the soil amelioration and dyke strengthening by warping, the methods for designing inlet and gate, delivery canal, dykes and release_drainage works; and the calculation methods of water diversion quantity and warping quantity, are proposed.
