哈尔滨地铁安通街大高差地形车辆基地的上盖物业开发设计

Superstructure Property Development Design for Harbin Metro Antong Street Vehicle Bases with Large Height Difference Terrain

我国的地铁车辆基地上盖物业开发设计大多基于同一轨面高程。大高差地形的地铁车辆基地上盖物业开发若采用常规的设计方案,会存在土石方工程量较大,以及难以和周边的城市规划有效衔接等问题。以哈尔滨地铁安通街车辆基地为例,在阐述该车辆基地用地条件及周边规划条件的基础上,结合工程特点及物业开发方案,分析了大高差地形车辆基地设计中影响物业开发的因素。提出分级场坪、设地下试车线、股道两侧路基支挡、桥建合一等技术措施,形成了1个地下试车线、2个分级场坪、3个降坡线路车辆基地设计方案。

Development and design of metro vehicle base superstructure property in China is mostly based on the same track surface elevation.For metro vehicle base with large height difference terrain,the development of superstructure property using conventional design solutions will have problems such as the excessive amount of earthworks and the poor integration with the surrounding urban planning.Taking Harbin Metro Antong Street Vehicle Base as an example,with an introduction of the land conditions of the vehicle base and the surrounding planning conditions,and combined with the project characteristics and property development plan,the factors affecting property development in the design of vehicle base with large height difference terrain are analyzed.Technical measures such as graded elevation,underground test line setting,roadbed retaining on both sides of the track,integration of bridge and building are proposed,which led to the formation of a vehicle base design scheme with one underground test line,two graded fields and three downward-slope lines.
