摘要： 西安市地铁三号线一期工程（鱼化寨~国际港务区）D3KC-2标段正线长度5695 m。为拟建各站点及区间的设计、施工，对太白南路站、吉祥村站、大雁塔北站三站水文地质条件进行了初步勘察，通过抽、注水试验，利用公式法计算得到各站潜水位以上各含水层的渗透系数及影响半径，三站最大渗透系数分别为1.48 m/d，2.38 m/d，6.89 m/d，最大影响半径分别为51.00 m，141.03 m，90.72 m。

关键词: 注水试验, 抽水试验, 渗透系数, 影响半径

Abstract: The first phase of D3KC2 bid package for No. 3 Line (between Yuhuazhai and International Port) of Xi'an Subway Project involves the construction of three subway stations (Taibai Road South, Jixiang Village and Great Goose Pagoda North) and subways that link these stations. The total length of the subway alignment is 5,695 m. This paper presents the hydrological investigation results for the design and construction of these facilities. The permeability coefficients and their influence radius of soil materials above the groundwater line are measured throughout the pumping and recharging tests. The maximum permeability coefficients are these stations are: 1.48 (m/d), 2.38 (m/d), 6.89 (m/d), respectively. Their influence radius are: 51.00, 141.03 and 90.72 meters, respectively.

Key words: groundwater pumping tests, groundwater recharging tests, permeability coefficient, influence radius
