| 摘 要： | 含水介质的空间分布及其非均质性对地下水流和溶质运移有着重要的影响。以淮南顾桥矿区作为研究对象,为了刻画矿区松散层含水介质的空间分布,使用转移概率地质统计方法建立含水介质的随机模型,对矿区水文地质结构的空间连续性和空间变异性进行表征;并将随机模拟得到的顾桥矿区含水介质剖面图与矿区原始水文地质剖面进行对比。结果表明,基于转移概率地质统计模拟方法可以比较准确地刻画矿区的水文地质结构;模拟剖面与原始水文地质剖面的比较显示模拟结果与实际含水介质空间分布情况有较好的一致性,转移概率地质统计方法在对含水介质非均质性刻画中具有较好的适用性。

| Abstract: | Spatial distribution and heterogeneity of aquifer medium have critical influence on groundwater flow and solute transport. To characterize the spatial distribution of aquifer medium, the Guqiao mining area in Anhui Province was investigated, and the stochastic model of aquifer medium was established through transition probability geostatistics. We characterize the spatial continuity and variability of the hydrogeological structure of the mining area. Moreover, the local simulated profiles obtained by stochastic simulation were compared with the original hydrogeological profiles. Our results show that the conditional simulation method based on transition probabilities can accurately depict the local hydrogeological structure. Comparing the simulated profiles with the original ones, we found that the simulated results are consistent with the actual spatial distribution of the aquifer medium. This shows that the transition probability geostatistics approach can well adapt to characterize the he-terogeneity of aquifer medium. |
