合肥地铁6号线潜水位与降雨量的关系研究

Relationship between phreatic level of Hefei Metro Line 6 and rainfall

以合肥市地铁6号线7个连续站点为研究对象,收集整理7个站点的水文地质资料以及一年的潜水位变化情况,发现潜水位标高呈现出雨季升高枯季下降的规律,地下水位标高最大值出现在7、8月份,地下潜水位的涨幅不超过5.13 m。将地下水的变化与合肥市降水量联系在一起进行分析,得出地下水位与降雨量的线性函数,相关系数最大达0.895,表明降雨量和地下水位存在明显的线性关系。

Taking 7 consecutive stations of Hefei Metro Line 6 as the research object,the hydrogeological data of 7 stations and the change of phreatic level in one year were collected.It is found that the elevation of the phreatic level shows the law of the increase of the dry season and the decline of the dry season.The maximum value of the groundwater level appears in July and August,and the increase of the underground phreatic level does not exceed 5.13 m.The groundwater changes are linked with the precipitation in Hefei City to analyze the linear function of groundwater level and rainfall.The correlation coefficient is up to 0.895,indicating that there is a clear linear relationship between rainfall and groundwater level.
