新疆叶尔羌河苏盖提吐乎防洪工程设计研究

Study on the Design of the Flood Control Project of Sugetihuhuin Yeerqiang River of Xinjiang

通过分析叶尔羌河主要发育4种类型洪水,依靠喀群站和依干其渡口水文参数,利用线性插值的方法确定苏盖提吐乎段的防洪参数。通过方案比选,选取斜坡型堤防和全断面浆砌石+现浇混凝土堤防结构具有稳定高、施工简便、工程投资低等特点,通过验算稳定性满足要求,可为叶尔羌河乃至新疆防洪工程设计提供参考。

Based on the analysis of the four types of floods mainly developed in Yeerqiang River,the flood control parameters of sugetihuhu section are determined by the method of linear interpolation based on the hydrological parameters of Kaqun station and yiganqi ferry.The slope type embankment and the full section masonry+cast-in-place concrete embankment structure selected through the scheme comparison are characterized by high stability,simple construction and low project investment.The stability is verified by calculation meet the requirements qualitatively.It can provide a reference for the design of flood control works of Yeerqiang River and even Xinjiang.
