摘要
城市地下轨道交通已成为城市交通的重要模式,城市地铁在城市交通运输中也起到了越来越重要的作用。自1863年伦敦建成世界上第一条地下铁道,迄今地铁建设已积累了130余年的经验与理论成果,在地铁隧道设计与施工方面的技术水平越来越成熟。我国地铁建设事业起步较晚。改革开放以来,随着国民经济的不断发展,我国的城市化进程也在逐步加快。经济的发展,人们生活水平的提高,城市规模的扩大,城市人口的急剧增加,城市交通面临着严峻的局势,就在这时,地铁建设才越来越多的进入到人们的视野里。
本设计为青岛市地铁3号线汇泉广场站3号出入口结构设计,运用荷载-结构法进行隧道衬砌结构力学计算,利用规范规定、工程类比、理论推导等多种方法结合进行结构设计,如对于隧道断面形状尺寸的设计采用工程类比法借鉴青岛市其他地铁隧道工程经验,利用规范规定方法进行材料系数选取、隧道深浅埋判断荷载计算、衬砌结构配筋等,利用理论推导及数值近似方法进行隧道衬砌内力、弹性抗力计算。

Abstract
Urban underground rail transportation has e the important mode of urban transportation, and urban subway plays an increasingly important role in urban transportation.. Since 1863 London built the world's first underground railway, subway construction has accumulated more than 130 years of experience and theoretical results so far, the design ofand construction of metro tunnel technology became more and more mature. China's subway construction began late. Since the reform and opening up, along with the continuous development of the national economy, our country's urbanization process is gradually accelerated. Economic development, people's living standards improve, the expansion of city scale, the rapid increase of urban population, urban traffic facing a grim situation, at this moment, the subway construction to more and more into the people's vision.
The design for the Qingdao City Subway Line 3, Huiquan Square Station No. 3 out of inlet structure design, the use of load structure method for tunnel lining structure mechanics calculation, use a variety of methods such as specification, engineering analogy, theoretical derivation with structural design, such as for tunnel cross-section shape and size design of the engineering analogy method from Qingdao city subway tunnel engineering experience, for coefficient of material selection, the tunnel depth buried to determine the load calculation, lining reinforcement using sta
