示踪试验在济南泉群优势补给径流通道研究中的应用
|
摘要
为查明济南泉群优势补给径流通道分布情况,提高补源保泉工作效率,本研究以寒武系张夏组含水层、凤山组含水层以及奥陶系马家沟组含水层为主要研究对象,以钼酸铵为示踪剂在济南南部山区不同含水层进行两次示踪试验,并在趵突泉、五龙潭等泉群中检出示踪剂。试验结果表明:地下水流速、示踪剂平均流速、示踪剂扩散速度等时线及检出点示踪剂历时曲线可作为优势补给径流通道识别特征,地下水优势径流补给通道受透水断裂控制。
In order to find out the preferential runoff path of Ji'nan springs and improve the efficiency of artificial recharging spring,two tracers have been tested using ammonium molybdate as tracer in the southern mountainous area of Ji'nan. In the study,the aquifer of Cambrian Zhangxia,Fengshan and Ordovician Majiagou are the main object. The tracer is detected in Baotu Springs,Wulongtan springs,etc. The results show that groundwater flow velocity,tracer mean velocity,isochrone of tracer diffusion and tracer curve can be used as the characteristic of preferential runoff path recognition. The preferential runoff path is controlled by permeable rift zone.
