| 摘 要： | 结合西安市城市轨道交通线网与地下水层的关系,分析轨道交通线网规划实施对地下水补给、径流和排泄的影响途径.采用数值模拟方法,利用Visual MODFLOW软件模拟轨道交通线网建设对地下水流场的影响.结果表明:轨道交通线网对地下水的影响主要发生在潜水层,在该水层形成多个封闭的"井"字形区域,在一定程度上减少了含水层的过水断面,导致局部区域地下水位壅高,局部区域地下水位下降,在水位抬升区或水位下降区,潜水位的变幅仅为0～1.25m.

| Abstract: | Considering the relationships between rail transit networks and groundwater aquifers in the city of Xi'an,the effects of rail transit network planning implementation on ground recharge,runoff and discharge were analyzed.The impacts of rail transit network construction on groundwater flow fields were simulated using Visual MODFLOW.The results show that influences occur in the unconfined aquifer and thus several enclosed square-formed areas are formed.It can reduce wetted area of the aquifer to some extent an... |
