摘要

研究目的：在地下车站设计中一般将车站主体结构设置一定的纵坡以满足地下车站纵向排水需求，但设置纵坡不仅增加了车站土建施工难度，也对后期的设备安装、装修等带来了诸多不便。本文从地下车站设置纵坡的原因、所存在的问题入手，结合工程实际情况，提出并研究地下车站采用平坡的设计方案。

研究结论：经过研究对比，地下车站主体结构采用平坡、在车站底板设置沿车站纵向的“人”字形双向排水沟的设计方案满足国内相关规范要求及车站功能需求，且有利于降低土建结构及后期装修施工难度、提高土建结构施工精度、减少设备安装处理工序、避免与其他接建工程的高差处理，工程总投资较常规纵坡车站方案增加较少。因此推荐在国内城市轨道交通工程中广泛采用。

Abstract

Research purposes:For meeting the demands of longitudinal drainage，the subway station structure has a longitudinal grade．The longitudinal grade not only makes the civil engineering more difficult，but also makes the equipment installation and the architectural decoration more uneasy． Based on the analysis of the reason for building the longitudinal grade and the problems in the engineering practice，this paper presents the design plan of building a level grade plan to subway station structure ．

Research conclusions:Based on the contrastive analysis，the drainage plan of building a longitudinal level grade to the main structure of the station and a bidirectional herringbone drainage under the station bottom is presented． It not only can meet the demands of the station function and the requirements of the corresponding standards in China，but also can reduce the difficulties of the construction and architectural decoration，enhance the precision of the civil engineering，decrease the process of the equipment installation，avoid the treatment of the elevation difference with other interrelated engineering and lowering the additional investment compared with the conventional longitudinal grade．In consequence，it is suggested to use the level grade widely in urban rail transit．
