基于GMS的玉符河人工补源影响研究
|
摘要
为探究济南市玉符河人工补源对趵突泉泉域的影响,在系统分析泉域水文地质条件的基础上,采用地下水数值模拟软件GMS10.0建立了2012—2014年覆盖趵突泉泉域的地下水流数值模型,通过模型对玉符河补源实施后地下水的径流方向、影响面积以及对泉水位和西郊水源地水位的提升作用进行评估。结果表明:玉符河补源在实际渗漏量为10.52×10~4m~3/d的情况下,玉符河补源水首先沿着炒米店地堑由南向北流,然后再向东、西方向径流。补源后第177 d,补源影响范围基本抵达四大泉群,玉符河补源的最大影响范围为485.79 km~2。玉符河补源对趵突泉、黑虎泉的最大影响水位为0.06 m和0.04 m;对济南西郊水源地的水位起到明显的提升作用,最大值达到0.57m。西郊水位的抬升可以缓解地下水开采对趵突泉水位的影响,减小保泉的压力,也为将来济南百姓重新喝上优质地下水奠定了基础。
In order to explore the effect of artificial recharge of Yufu River on the Baotu Spring domain,the groundwater numerical simulation software GMS10.0 was used to analyze the hydrogeological conditions of the spring domain. Groundwater flow numerical model of the Baotu Spring domain was established in 2012 and 2014 to elevate the runoff direction,the influence area of the groundwater,the enhancement of the water level in the spring water level and the western part of the water source after the artificial recharge of Yufu River. It is showed that the recharge water of Yufu River is firstly supplied from south to north along the Chaomidian graben,and then to the east and west. 177 days after the source is compensated,the maximum influence range of the group is 613 km2. The maximum impact on water level of Yufu River for Baotu Spring and Heihu Spring is 0.06 m and 0.04 m,and the water level of western suburbs water source is obviously improved,the maximum value is 0.57 m. The water level of the western suburbs can alleviate the impact of groundwater exploitation on the water level of Baotu Spring,reduce the pressure of protection of springs in Jinan,and also lay the foundation for the people of Jinan to re-drink high quality groundwater in the future.
