Abstract: As a new type of rail transit, maglev vehicles have smaller underground stations compared to traditional subway stations due to their small vehicle composition. In order to explore tunnel ventilation modes suitable for maglev underground stations, this paper draws lessons from the traditional subway station tunnel ventilation mode, and creatively discusses four kinds of tunnel ventilation modes of maglev underground station. The operation mechanisms of four tunnel ventilation modes under normal operating conditions, blocking conditions and fire conditions are analyzed. Through the table quantitative analysis of the energy consumption, mechanical and electrical cost and civil construction cost of the four tunnel ventilation modes, it is concluded that the mode four interval tunnel double-piston ventilation + station single-end double-row hot fan system is the best tunnel ventilation mode suitable for maglev underground station.
Keywords: maglev underground station; tunnel ventilation mode; energy consumption; cost; new rail transit
城市軌道交通已經(jīng)成為人們出行的必要工具,也是打造綠色城市的重要環(huán)節(jié),怎樣讓城市軌道交通更加節(jié)能增效是值得研究的問題。城市軌道交通項目能源消耗主要表現(xiàn)為電力消耗,其中車站通風空調(diào)耗能在車站總體耗能中占較大比例,而車站隧道通風耗能占整個車站通風空調(diào)能耗的15%。目前城市軌道交通如地鐵車站的區(qū)間隧道通風模式多采用雙活塞系統(tǒng),車站隧道通風模式多采用兩端設置排熱風機形式。磁浮系統(tǒng)作為一種新型的城市軌道交通車輛,其對應的線路和車站在城市中多以高架敷設,但是部分項目由于各種外在條件制約,仍然需要考慮地下敷設。由于磁浮車輛編組較短,車站規(guī)模較小,本文參考傳統(tǒng)地鐵地下車站的隧道通風模式,創(chuàng)新地探討磁浮地下車站的隧道通風模式,同時對比各個模式的耗能及造價。……
