摘　　要：为节约城市土地资源,缩短施工周期,提高市域铁路区间桥隧过渡段箱式变电站的经济性与可靠性,对市域铁路区间桥隧过渡段的箱式变电站布置方案进行比选。考虑市域铁路区间不同过渡段的不同工况,区间变电站布置设定4种方案:(1)区间变电站设于高架桥下;(2)区间变电站与雨水泵房合建;(3)区间变电站设于隧道口上方;(4)区间变电站设于U槽敞开段两线间。对市域铁路区间桥隧过渡段箱式变电站不同布置方案的优缺点进行了分析,针对性地提出区间各过渡段的最优方案。To save urban land resources,shorten the construction cycle and improve the economy and reliability of box-type substation in city railway interval bridge-tunnel transition segment,the arrangement scheme for the box-type substation of this condition is compared and selected.Considering the different working conditions of various city railway interval transition segments,four interval substation arrangement schemes are formulated:(1)interval substation is located under viaduct bridge,(2)interval substation is built with the rainwater pump room,(3)interval substation is located above tunnel entrance,(4)interval substation is located between the two lines of the U-trough open segment.By analyzing the advantages and disadvantages of different box-type substation arrangement schemes for the city railway interval bridge-tunnel transition segment,the optimal scheme specifically for each transition segment in the interval is proposed.
