长沙市地铁1号线人民路车站施工方案设计
摘要
长沙地铁1号线一期工程从汽车北站到万家丽路站,呈南北走向,从汽车北站到芙蓉路,穿越浏阳河后,到达营盘路,后面改走黄兴路,然后与长沙地铁2号线相交于五一广场,之后继续向南走,最后到达了万家丽路。
人民路车站位于黄兴路步行街和人民路交叉处的北边,车站所处的位置是长沙市最为繁华的商业地段,在人流密集、商铺繁多的步行商业街处修建地铁车站,既要使周边建筑保持稳定和确保步行商业区的交通正常运行,同时保证在有限的空间内提供施工场地条件,是长沙市地铁1号线20座车站中距离周边建筑、最近施工条件最复杂的车站之一。
本站设计主要是对地铁车站进行车站主体结构进行设计,其设计内容包括:车站主体结构设计,车站防水设计,车站的施工方案设计,施工组织设计和基坑支护设计。
车站采用地下两层岛式站台,施工采用盖挖逆筑法施工,支护结构采用地下连续墙支护。
