南水北调中线吴庄隧洞工程设计要点

摘要

阐述了南水北调中线吴庄隧洞工程洞型断面的选择，隧洞进出口位置、进口底高程、洞身结构尺寸、进出口分流角和汇流角的确定等关键性控制体形尺寸的原则和方法，以及洞身支护参数的选择与衬砌结构计算，可供类似输水隧洞设计借鉴。%This paper expounds the hole section of South-North Water Transfer Project Wuzhuang tunnel project selection , principle and methods to determine the key control size of tunnel import and export position, imported bottom elevation, hole body structure size, import and export diversion angle and the confluence angle, as well as the calculation methods of tunnel supporting parameters and lining structure. A positive reference for similar tunnel design.
