裁弯取直技术在黄河下游大宫至王庵河段的应用

Application of the Engineering Technology of Curving Cut-off in the Reach from Dagong to Wang'an in the Lower Yellow River

黄河下游为典型的游荡性河段,横河、斜河等畸形河势时有发生,从理论和实践两方面论证了裁弯取直工程是规顺黄河下游畸形河势、减小两岸工程出险几率的一种有效措施.着重介绍了黄河下游大宫至王庵河段裁弯取直工程的方法和措施,可作为其他畸形河势治理时参考.

The Lower Yellow River is typical wandering reach. Abnormal river pattern such as transverse river, inclining river, etc. are prone to be formed. It is proved from theory and practice that the engineering technology of curving cut-off is an effective measure to regulate the abnormal river pattern, and to decrease the rate of river works in danger in the Lower Yellow River. Engineering methods and meassures to curve cut-off in the reach from Dagong to Wang＇ an are mainly introduced in order to supply reference for abnormal river pattern training.
