补充资料：渡槽
| 渡槽 aqueduct 输送渠道水流跨越山谷、洼地、河渠、道路的架空水槽。常用的渠系交叉建筑物。除用于灌排外，也可用于泄洪、排沙和通航。其建筑材料有木材、浆砌石、混凝土、钢筋混凝土和钢材。渡槽由 4部分组成。① 进出口段。分别与上下游渠段顺畅相接，使水流平稳，且防冲、防渗。进口或其前常设闸门。② 槽身。起输水作用，横断面多呈矩形、U 形、梯形等。③支承结构。将上部荷载传给基础，再传至地基。分为：梁式，采用重力式槽墩、钢筋混凝土排架和桩柱式排架等；拱式，由墩台、主拱圈和拱上结构组成；桁架拱式，按结构特征和槽身在桁架拱上位置的不同，又分为上承式、中承式、下承式及复拱式；斜拉式，由塔墩上的塔架引出斜拉索悬吊支承槽身荷载 。④ 基础。将渡槽全部荷载传给地基。公元前700年左右，西亚的新亚述帝国曾建成长约300米、宽13米，有 14 个墩座的巨型渡槽。据记载中国西汉已有渡槽，距今已逾两千年。
