南水北调中线穿黄工程渡槽设计研究

根据南水北调中线穿黄河段的地形地质条件，黄河的洪水泥沙特性和穿黄工程规模大，技术复杂的特点，进行了多种方案的研究比较，推荐采用三向预应力矩形薄腹梁渡槽，下部结构为柱式墩，混凝土灌注桩基础。经过较全面的设计分析研究，渡槽能够满足各种可能条件下的施工和安全运行要求。

Design and Study on Aqueduct of Middle Route of Cross the Yellow River Work of Water Transfer Project from South to North

According to the characteristics of topographic and geological conditions of the section where the middle route of the Water Transfer Project from South to North will cross through, the characteristics of floods and sediment of the Yellow River, a grand scale and complicated in technology, the paper recommends and adopts a plan of three-dimensional pre-stress rectangular aqueduct with thin and narrow beams after studying and comparing many scenarios. The lower part structure of the plan is column pier and grouted concrete foundation. After calculation, analysis and study in an all-round way, it shows that the aqueduct can meet the requirements of construction and safe operation under any possible conditions.
