武汉大学白莲河灌区龙潭冲渡槽设计说明书 武汉大学 白莲河灌区龙潭冲渡槽设计说明书 - - PAGE 10 - 内 容 摘 要 本次设计作为农水专业本科生的毕业设计，主要目的在于运用所学的有关专业课，专业基础知识及基础课等的理论；了解并初步掌握水利工程的设计内容，设计方法和设计步骤；熟悉水利工程的设计规范；提高编写设计说明书和各种计算及制图的能力。 根据设计任务书，说明书分为四章。第一章，基本资料。第二章，整体布置，确定渡槽的线路和槽身总长度，进行水利计算，确定槽底纵坡以及进出口高程。第三章，槽身结构设计，确定槽身的横断面尺寸，进行槽身 纵横断面内力计算及结构计算。第四章，支承结构设计，确定支承结构的尺寸， 进行支承结构的结构计算，渡槽基础的结构计算及渡槽整体稳定性计算。 Abstract This design is a graduation project of undergraduation. Its main aim is to apply what have been learned in class, such as specialized courses, specialized basic courses, basic courses and so on, to initially master the content of design, the methods of design, the steps of design of the irrigation project; to have an intimate knowledge of the design standard of the irrigation project; to raise the capacity to compile the design exposition and the capacity of calculation and drawing. According to the task, the design exposition is made up of four chapters. Chapter one is the basic material. Chapter two is assignment on the whole, in which the aqueduct line and total length are decided, and make the hydraulic design to decide the slope of bottom and the altitude of exit and entrance. Chapter three is the structure design of aqueduct body, in which the cross section of aqueduct body is decided, and calculate the internal force and the structure of cross section and vertical section. Chapter four is the structure design of support structure, in which the dimensions of support structure are decided, and calculate the internal force and structure of support structure , and calculate the structure of aqueduct foundations, and check the stability of aqueduct on the whole. 目 录 内 容 摘 要 1 Abstract 2 第一部分 设计说明书 5 第一章 基本材料 5 第二章 整体布置 7 第三章 槽身结构设计 9 第四章 支承结构设计 14 第一节 支承结构型式及尺寸的拟定 14 第二节 槽墩与槽架的结构计算 15 第三节 排架的基础结构 18 第四节 渡槽的整体稳定性验算 19 第二部分 计算书 21 槽身的水力设计 21 拟定槽身的纵坡i、净宽B 0 和净深H  21 0 渡槽的进出口高程计算 22 槽身纵向内力计算及配筋计算 24 荷载计算 24 内力计算 25 正截面的配筋计算 26 槽身纵向抗裂验算 27 斜截面抗剪计算 29 槽身横向内力计算及配筋计算 29 ⑴底板的结构计算 30 ⑵侧墙的结构计算 32 ⑶肋的结构计算 33 边墩的结构计算 44
