潼关至三门峡河段治理回顾及对策研究

Historical harnessing the Tongguan-Sanmenxia Reach and Further Measures

三门峡库区潼关至三门峡河段两岸的地形、地质条件复杂 ,塌岸损失情况严重。分析认为 ,库区上段工程布局不合理 ,河势游荡多变 ,是引起库岸严重坍塌的主要原因 ;库区中下段护岸工程少 ,质量差 ,塌岸仍在继续发展。鉴于此 ,今后应对库区上段进行河道整治 ,中下段进行防冲防浪工程建设。

Introduction of the banks topography, local geological conditions, bank collapses from Tongguan to the Sanmenxia dam and the historical harnessing progress has led to the awareness of the existing problems. Unreasonable layout of the works in the upper part and main streamline migration are mainly responsible for bank collapse. There are fewer embankments. The existing embankments are of bad quality. Banks continue collapsing. The proposal for the harnessing is to effect channel improvement in the upper part, and to construct the works against waves and erosion.
