城市復(fù)雜環(huán)境下暗挖地鐵車站綜合降水方案研究

打開文本圖片集

【摘    要】：針對暗挖地鐵車站傳統(tǒng)地面管井降水施工受到復(fù)雜條件的影響，難以實(shí)施或形成封閉降水條件的難題，以北京地鐵某暗挖車站為例，通過精細(xì)化分析車站周邊環(huán)境條件及工程地質(zhì)、水文地質(zhì)條件，采用導(dǎo)洞降水井、單邊減壓降水、傾斜井點(diǎn)疏干降水等綜合降水方案處理地下水。

【Abstract】：In view of traditional surface pipe well dewatering construction of underground stations is affected by complex conditions， so it is difficult to implement or form closed dewatering conditions， taking a underground station of Beijing Metro as an example， through a refined analysis of the station's surrounding environmental conditions and engineering geological and hydrogeological conditions， the comprehensive dewatering schemes such as pilot tunnel dewatering wells， unilateral decompression dewatering， and inclined well point dewatering dewatering are adopted to treat the groundwater.

【Key words】： metro; underground excavation station; groundwater;dewatering in pilot tunnel
