南水北调中线青兰高速交叉渡槽工程是总干渠上的大型交叉建筑物。由于规划阶段未对其分配额外水头，且需兼顾已建高速公路引线工程布置，给渡槽的设计带来了极大困难。为此，设计创新性地提出了过水断面为梯形、槽身结构为分离式扶壁梯形、在顺流向平面上呈不对称斜平行四边形布置的渡槽结构。结构布置和设计新颖而独特，成功解决了相关技术难题，可为类似渡槽工程设计提供借鉴。

The aqueduct over-passing Qingdao-Lanzhou Highway is a large type crossing structure on the main canal of Mid-dle Route Project of South-to-North Water Diversion. Because an additional water head was not designed in the planning stage and the approach road of built highway should be considered, the aqueduct design has encountered great difficulties. This paper innovatively puts forward the trapezoidal cross section with separated buttress and a flow-direction asymmetric slant parallelogram in plane. This structure layout is unique and original, and successfully solves the technical difficulties, which can be referred by similar projects.
