潮白河水源地地球物理勘查

Geophysical Explorationin in the Water Source of Chaobai River

潮白河水源地位于潮白河顺义段,是北京市重要供水水源地之一。在潮白河地下水源地核心区开展音频大地电磁和可控震源地震勘查,依据地球物理特征参数电阻率、地震波速地球物理场特征变化规律。查明潮白河地下水源地核心区典型段松散含水层结构特征,呈现条带状缓坡结构,属典型山前冲洪积水系古河道层状异常规律,且各含大层上下贯性通性好,为水源地地质建模提供基础数据,进而为水源地合理开发利用提供技术支持。

The water source of Chaobai River is one of the most important water supply sources in Beijing, located at Shunyi in the Chaobai River. According to the changing rule of different geophysical characteristics parameters, audio magnetotelluric sound-ing and vibroseis seismic exploration are carried out in the core area of underground water source of Chaobai River with the purpose of finding out the structural features of the unconsolidated aquifer in the typical district of Chaobai River. The explorations not only supply the basic data for the 3D geologic modeling, but also provide the technical support to the reasonable development and utiliza-tion of the water source of Chaobai River.
