甘肃白银市昌元化工拟建区水文地质条件研究

The hydrogeological conditions of proposed construction area ofChangyuan chemical industry in Baiyin City, Gansu Province

研究表明,拟建区地下水受地表水和大气降水控制较明显,地下水化学类型稳定,以SO _(4)·Cl—Na,Cl·SO_( 4)—Na型水为主,对拟建工程影响较小;每年8—9月地下水水位较高,在该时期施工应注意地下水突水问题;目前,勘查区无地下水开发利用现象,亦无环境保护目标,故施工对该区域地下水影响较小。

This study showed that the groundwater in the proposed construction area were obviously controlled by surface water and atmospheric precipitation.The chemical types of groundwater were stable,dominated by SO_( 4)·Cl—Na,Cl·SO_( 4)—Na water,which had little influence on the proposed construction project.The groundwater showed a high level from August to September every year,so groundwater inrush during this period should be noticed.At present,the groundwater hadn′t been developed and utilized in the exploration area,and there is no environmental protection target.Therefore,the construction had little impact on the groundwater in the area.
