摘要 南水北调中线工程总干渠河北省南段线路以冀豫交界处的漳河北为起点，沿京广铁路西侧的太行山东麓自南向北，经过河北省邯郸、邢台、石家庄3市及所属11个县（市），至京石应急供水段起点为止，渠道长222.593km，建筑物长14.655km. 黄岗渡槽是南水北调工程总干渠上的一座跨渠输水建筑物，与总干渠交叉点桩号为10+437（黄岗渡槽位置详见总体布置图）。根据总干渠可行性研究阶段已确定的工程等级及建筑物级别，本渡槽为1级建筑物，抗震设防烈度为Ⅶ度。 考虑经济,施工难度等方面的因素,结合工程有关条件,渡槽设计为的（无拉杆）矩形梁槽身。 设计分为上部结构和下部结构的设计,上部结构设计包括尺寸拟定和配筋计算，其中又包括跨中截面尺寸的拟定，截面特性的计算，永久作用、可变作用的计算及其组合。槽身验算主要为承载能力极限状态计算,正常使用极限状态计算以及槽身的配筋计算及验算和变形验算,经计算各项指标均符合设计。 下部结构的设计以排架设计和桩基础的设计为主要内容.包括排架结构形式的确定,尺寸的拟订,排架结构的配筋计算和桩基础的荷载计算，及其桩长计算等。各项检算也均符合要求。 关键词：输水建筑物渡槽；；排架 Abstract South-North Water Transfer Project in Hebei province south of the trunk line to the junction of Yu Ji Zhang Hebei as a starting point, Jing-Guang Railroad along the west side of the Taihang Mountain Donglu from south to north, after Handan, Hebei Province, Xingtai, Shijiazhuang City, and their 3 11 counties (cities), emergency water supply to Jingshi paragraph starting point, the channels of 222.593 km, the building of 14.655 km. Huang Gang is the diversion Aqueduct works on the trunk of a cross-water drainage structures, with the main channel for cross-point Zhuanghao 10 +437 (Huanggang Aqueduct see the overall layout of location). According to the Channel feasibility study stage of the project have been identified and grade-level buildings, the aqueduct for a building, seismic fortification for the intensity of Ⅶ. Consider the economy, the difficulty of such factors, the conditions of work, the aqueduct is designed to 119.42 m (with drawbars) rectangular beam trough body. Design of the structure is divided into upper and lower structural design, structural design including the upper part of the development and reinforcement size, which also included cross-section size in the formulation, cross-section of the calculation, the permanent role, the role of variable calculation and combinations. Slot for the main body checking carrying capacity limit state basis, the calculation of normal use limit state and the reinforcement shafts are calculated deformation
