多水系交互沉积区的地质及水文地质特征十分复杂,传统的分区方法往往会存在工作量大、人为因素多的不足。该文以北京通州运河核心区为例,首先利用翔实的地质资料进行了多水系交互沉积区地质及水文地质特征分析,然后利用地质3D技术,建立了研究域40m深度范围内地层分布的3D模型,结合区域水文地质条件,系统地提出了研究域工程水文地质分区。最后,进行了研究域内地下水位动态特征相似性分析,分析结果进一步说明了分区的合理性。
The geological and hydrogeological features of the multi-water system interactive sedimentary area are very complex. The traditional method of zoning usually has the problems of heavy workload and many human factors. Taking the core area of Tongzhou Canal in Beijing as an example, the geological and hydrogeological features of the multi-water system interactive sedimentary area were first analyzed with detailed geological data. Then, by using the 3D geologic technology, a 3D model of formation distribution in the depth of 40 m was established , Combined with the regional hydrogeological conditions, systematically proposed research area hydrogeology zoning. Finally, the similarity analysis of the dynamic characteristics of the groundwater table in the study area is carried out. The analysis results further illustrate the rationality of zoning.
