乌鲁木齐地铁2号线哈马山车辆基地方案研究

国内对西北地区地铁车辆基地总平面布置、屋架结构形式及屋面采光方案的系统研究较少。从乌鲁木齐地铁2号线哈马山车辆基地的选址用地入手,通过分析段址环境及出入段线接轨条件,对场坪高程确定及总平面布置方案进行研究。通过对国内工业厂房普遍采用的钢筋混凝土柱支承网架结构、钢筋混凝土柱支承梯形钢屋架结构及门式刚架结构的特点进行对比分析,从节省用钢量及便于库内上部管线的布置角度推荐采用钢筋混凝土柱支承网架结构形式。通过对屋面三角形天窗、采光带/采光板及矩形天窗的特点进行对比分析,从采光效率及不易被积雪覆盖角度推荐采用三角形天窗形式。

Research on the Scheme of Hamashan Vehicle Base of Urumqi Metro Line 2

There are only a few systematic studies on the general layout of the subway vehicle base,the structure of roof truss and the lighting scheme of roofing in the northwest of China. This paper focuses on the site selection of Hamashan vehicle base of Urumqi Metro Line 2,analyzes the conditions of the segment environment and the access line,and studies the elevation of the field and the general layout.Through comparison and analysis of the characteristics of reinforced concrete column-supported grid structure, reinforced concrete column-supported trapezoidal steel roof truss structure and portal frame structure adopted in domestic industrial factory buildings,the reinforced concrete column support grid structure is recommended from the point of saving steel consumption and easy upper pipeline configuration.By comparing the characteristics of triangular skylights,lighting belts/lighting panels and rectangular skylights,the triangular skylight form is recommended in view of lighting efficiency and freeing from snow covering.
