●华县防护大堤工程华县防护大堤位于渭河右岸,全长76.85公里,其中大堤29.85公里,支堤47公里,工程始建于1960年,后经四次加高培厚,设计防洪标准为50年一遇10800m~3/s洪水,堤顶高程343.00～350.00米,顶宽6米,临背差2～3米,防护区保护10万人口,24万亩土地。由于加高培厚施工质量较差,实际防护能力仅能防御渭河12年一遇7660m~3/s洪水,为了提高工程的防洪能力,陕西
● Huaxian Protective Levee Project Huaxian protective levee is located on the right bank of the Weihe River, with a total length of 76.85 kilometers, of which 29.85 kilometers of levee and 47 kilometers of embankment. The project was started in 1960 and after four times of thickening and thickening, the flood control standard is 50 years In case of 10800m ~ 3 / s flood, dike top elevation 343.00 ~ 350.00 meters, the top width of 6 meters, the poor back 2 to 3 meters, protected areas 100,000 population and 24 million mu of land. Due to the poor construction quality, the actual protection ability can only prevent 7660m ~ 3 / s flood once in 12 years in Weihe River. In order to improve the flood control ability of the project, Shaanxi
