摘要
为构建潮白河地区三维地质结构、地下水渗流模型及溶质运移模型,应用瞬变电磁法和电测深法联合勘测技术勘察潮白河地区水文地质,圈定了新生界(100 m深度以浅)砂砾石层、黏土层异常分布以及砂砾石层上下连通异常区,所得物探成果与研究区现有大量钻孔资料所形成的地质剖面基本吻合,验证了两种方法联合勘测能大大提高水文地质勘察的准确性和效率。
In order to build the three-dimensional geological structure, the model of groundwater flow and the model of solute transport in Chaobai River, transient electric magnetic technology bonding with electric sounding technology were applied to explore its hydro-geology. The distribution of sandy-gravel and clay within lOOm depth were identified, and the connectivity of sandy-gravel layers was also detected. Compared with that information of drill holes, the results were highly similar to the geology section obtained from those holes, which suggested these technologies combined together can greatly improve the accuracy and efficiency of hydrology exploration.
