三门峡库尾的泥沙淤积及其解决途径的建议

Sedimentation Development at the End of the Sanmenxia Reservoir and A Proposal for Solving Way

本文着重分析了三门峡水库建成以来水库库尾淤积的发展情况，潼关河床高程的上升对渭河下游淤积发展有很大影响。潼关河床高程不能下降，给潼关以上库区人民生活和生产的安定，甚至对关中平原的工农业生产带来严重影响。本文在认清规律的基础上，提出了用挖泥船清除潼关至古夺河段泥沙淤积的必要性。

This paper concentrates on the analysis of sedimentation development at the end of the Sanmenxia Reservoir after its completion.The increase of Tongguan Bed Elevation(TBE)has great influence on sedimentation development at the lower reaches of the Weihe River.The maitenance of TBE significantly affects the life and production stabilities in the reservoir region of upstream Tongguan and the industry and agriculture operations in Guanzhong Plain. Based on the sedimentation development law, this paper argues for the necessity of dredging at the reaches between Tongguan and Guduo.
