跨坐式单轨高架车站结构型式的选择

Structure Type Selection for Overhead Station in Straddle Type Monorail

对跨坐式单轨高架车站结构型式的选择,需根据其周边环境、城市规划、工程地质及水文地质条件、地下管网等综合因素确定。重庆轨道交通较新线为国内首条采用跨坐式单轨胶轮的城市轨道交通工程,其一期工程的高架车站有11座,按结构型式可分为门式刚架结构、单层独柱墩结构和双层独柱墩结构等3种;接结构受力体系可分为“建桥合一”和“建桥分离”2种结构。其高架车站结构选型可为我国其它类似工程提供借鉴。

The selection of structure type for the straddle monorail and overhead station is decided by the synthetic factors like the perimeter environment, city planning, engineering geology and hydrology geology, underground tube net etc. Jiaoxin Line, the first lightrail transit in Chongqing which adopts single track and overhead station structure,with 11 stations in the 1st phase, will be built in 3 different structures. The author argues that this line shall be the model for similar projects in China.
