摘 要

本设计根据站址环境和地质概况，按照地铁设计规范和混凝土结构设计规范等，本着经济合理、安全实用的原则，对南京地铁某站进行建筑设计、结构设计等。

论文重点研究的问题：1）车站总平面布置及平、纵断面设计；2）结构各工况内力计算及配筋设计；3）施工方案设计。

设计的主要思路：1）根据周边环境、经济、远期规划和施工方法确定总体平面布置及车站规模。2）建筑设计中以“适用、经济、美观、环保”作为设计原则。3）根据地面的交通状况和地下土层环境，选用明挖法施工。4）拟定车站主体结构尺寸，根据给定的设计地质及参数计算水土压力，根据地铁设计规范计算其它荷载和进行荷载组合，选择施工阶段、使用阶段、地震阶段的基本组合，采用荷载—结构模型，运用弹性地基梁的理论使用SAP2000分析软件对各阶段分别进行内力计算，根据计算出来的最大内力，按照混凝土结构设计规范对主体结构进行配筋计算；5)对常用的几种施工方案进行方案比选，进行车站主体的详细施工设计

关键词：地铁车站 结构设计 SAP2000结构计算 明挖法 施工方案

Abstract

According to the environment and geology situation as well as the code for design of metro and the code for design of concrete structures etc, this thesis accomplishes the architecture design, structure design and settlement analysis of PingAnLi subway station in WuXi in the principle of economy, reasonability, safety and practicality.

The main problems settled by this thesis are as follows: 1) the overall arrangement and the plane arrangement of the station; 2) the calculations of the loading combinations in every work condition, and the design of the distributed steel; 3) the schematic design of the construction.

The main thought of the design can be concluded as follows: 1) the plane form and the scale of the station is confirmed according to the surroundings, business request, long-term program, and construction method; 2) the architecture design is done according to the principle of “applicability, economy, good-looking, environment protection”; 3) the open cut method is adopted according to the ground traffic case and the underground soil environment; 4) study out the sizes of the major structure of the station, calculate water pressure and soil pressure according to geology and given parameters, work out the other loads by the code for design of metro and do combinations of the loads, choose the basic combination of the using stage, construction stage，and the earthquake using stage. adopt load- structure model, calculate the internal force of the structure in these stage by using of SAP2000 software with the method of plane elastic foundation beam,meanwhile, do calculation about steels collocating of the principal structure according to the biggest internal force calculated and the code for design of concrete structures; 5) compare some construction methods and design the way of construction particularly;

Key words：Subway station；Structure design；the procedure of SAP2000；The open cut method；Construction plan
