经济性与安全性对地铁设计方案的影响探讨

摘要

Taking Harbin subway Line No. 3 phaseⅡ starting point-Zhengyi road station district design scheme as an example,starting from the aspect of safety and economy,according to actual conditions,the paper determines to apply phase I engineering construction vertical shaft scheme,comparatively analyzes merits and defects of new construction No. 1 vertical shaft and using phase I engineering construction vertical shaft scheme,and studies regional large-section masonry size,which has certain guiding role for similar engineering.%以哈尔滨地铁三号线二期起点—征仪路站区间设计方案为例，从安全性与经济性的角度，对比分析了新建1号施工竖井与利用一期工程施工竖井方案的优缺点，依据实际情况，确定采取利用一期工程施工竖井的方案，并研究了区间大断面衬砌内轮廓尺寸，对类似工程具有参考作用。
