| 摘 要： | 王寨盆地是大武富水地段的一个特殊补给区，地质条件较为复杂，水文地质条件的研究相对较少，利用示踪试验对该区进行水文地质条件研究，是一种简单有效的方法。本次示踪试验采用钼酸铵作为示踪剂，历时75天，钼离子浓度历时曲线分为单峰型、双峰型和多峰型，地下水视流速平均值为23373m/d。通过试验揭示了王寨盆地岩溶发育特征为溶孔、溶隙、裂隙、管道、溶洞并存，地下水径流通道有单一管道型、单管道有水池型、多管道型和多管有水池型，具有多向性和复杂性；主要的地下水径流通道有3个，均汇入淄河断裂带；地下水流向以西南、东南、正东(东北)为主，整体流动较为缓慢，溶质的运移以正东(东北)方向最快；王寨断层和边河断层具有良好的导水性。因试验在枯水期进行，降雨量较小，地下水开采的日周期性影响也相对稳定，故试验时段地下水流场较稳定，试验结果所揭示的水文地质问题也较准确。

| Abstract: | The Wangzhai basin is a special recharge area for the Dawu water- rich district. It is characterized by complex geological conditions and study on its hydrogeological conditions is relatively poor. It is a simple and effective method to study hydrogeological conditions in this area by tracer test. The tracer test used Ammonium Molybdate as tracer lasted for 75 days. The duration curve of molybdenum ion concentration can be divided into single peak type, double peak type and multi- peak type. The average apparent velocity of groundwater is 233.73m/d. The experiment reveals that karst development of the Wangzhai basin is characterized by the coexistence of dissolution pore, dissolution gap, fissure, pipeline and karst cave, and channels for underground water contain single channel with or without tank and mutiple channels with or without tank. All the channesl are of mutiple directions and complexity. There are three main groundwater runoff channels, all of which lead to Zihe fault zone. The groundwater flows mainly to southwest, southeast and east (northeast) at a slower speed. Solutes migrate most rapidly to the east (northeast) direction. The Wangzhai fault and Bianhe fault have good water conductivity. Because the test was carried out in the dry season with less precipitation, and the daily periodic influence of groundwater exploitation was relatively stable, the groundwater flow field was relatively stable during the test period, and the test results reveal hydrogeological problems in a relatively accurate way. |
