《南水北调与水利科技》：大宁调压池工程分析与设计（张浩）（摘要）

摘要：大宁调压池是南水北调中线工程北京段总干渠上的调压建筑物，上游连接PCCP压力管道，下游连接钢筋混凝土低压输水暗涵，具有调节供水压力、供水流量和退水功能，对保证工程安全和供水安全具有重要作用。重点分析了调压池水位、池底面积、调节容积、池底高程等设计参数的确定方法和结果，介绍了工程方案比选、池壁挡墙和底板结构设计情况，并针对比较容易发生问题的变形缝处理和混凝土裂缝控制内容进行了专门说明。

Abstract:Daning Surge Tank,the surge structure of the Channel of the South-to-North Water Transfer (Middle Line)Project,connects the PCCP pressure pipe on upper course,and the water delivery underdrain on lower course with the function of adjusting the pressure and the flow rate of water delivery and the function of recession,which is important to the security of the project and the water delivery.The methods and result of the water level of tank,the area of tank bottom,the volume,and the elevation of tank top and bottom were analyzed.The confirmation of plan and the process of structure design were introduced.The design of deformation slot and the control of crack in concrete structure were specially presented.

Key words:South-to-North Water Transfer Project;Daning Surge Tank;analysis and design
