摘要: 首先阐述转移概率地质统计软件(T-PROGS)基本原理,然后充分利用已知钻孔的岩性信息,应用地质统计学条件模拟技术建立研究区水文地质结构模型;在此基础上,采用基于概念模型的方法建立研究区水文地质概念模型;最后通过水文地质单元流(HUF)软件包实现二者有机集成,最终建立和识别研究区地下水三维数值模型,水文地质参数以岩性赋值,并应用该模型进行水源地开发利用方案预测,得出水源地日供水8×104m3是有保障的,其可开采资源量为26.23×104m3/d。Abstract: The transition probability geostatistical software is introduced in this paper.On the basis of borehole data,the hydrogeological structure model in the study area is constructed by using geostatistics condition simulation,and the hydrogeological conceptual model in the study area is constructed by using conceptual model approach.With the aid of hydrogeologic-unit flow package,the integration and the 3-D numerical simulation of groundwater in the Liziyuan wellfield is built and calibrated,and the parameters are defined by lithology.By using this method,water supply of 8×10~4m~3/d in the Liziyuan wellfield is secured,and the safe yield is 26.23×10~4m~3/d.
