摘要：地铁出入口一般分为楼梯+扶梯组合式出入口、楼梯出入口、垂直电梯（无障碍电梯）出入口、垂直电梯（无障碍电梯）+楼梯组合式出入口等形式。本文对双垂直电梯+楼梯的深埋深暗挖地铁车站出入口建筑进行了研究，包括明确边界条件，分析建筑方案组成要点和环境景观融合，并与传统的扶梯+楼梯出入口方案进行技术和经济性对比，得出该方案不仅开挖工程量小，且地面建筑的占地面积也较小，在保障地铁安全运行的前提下，节约了造价、缩短了工期。
Abstract: The subway entrances and exits are generally divided into the combination entrances and exits of staircase +escalator,staircase entrances and exits, vertical elevator (accessible elevator) entrances and exits, vertical elevator (accessible elevator)+staircase combination entrances and exits, and other forms. This paper studies the deep-buried and deep-dug subway station entrance and exit building with double vertical elevators + staircase, including defining the boundary conditions, analyzing the key components of the building scheme and the integration of environmental landscape, and making a technical and economic comparison with the traditional escalator+stairs entrance and exit scheme. It is concluded that this scheme not only has a small excavation amount, but also has a small area of the ground buildings. Under the premise of ensuring the safe operation of the subway, the cost is saved and the construction period is shortened.
