水文地质声纳在晋江穿越中的应用研究

The Application of Hydrogeological Sonar in the Jinjiang Through

以西气东输晋江穿越中地下水渗流的声纳探测为例,介绍了三维流速矢量声纳测量仪的测量原理和测量方法。通过对晋江两侧钻孔地下水的渗流测量,查明了拟建场地的水文地质渗流运动形态,确定了地下含水层的渗流分布,给出了相关水文地质参数,为后期的设计和施工提供了重要指导依据。

The detection of sonar in groundwater seepage where west to east gas pipeline in the Jinjiang through was thaken as an example, where the principle and method of three-dimensional flow velocity sonar measuring instrument were presented. The groundwater seepage of the Jinjiang hole on both sides can be measured. The seepage form of hydrology geology is proposed, the seepage distribution of underground aquifer is determined, parameters are given, which will provide important guiding basis in design and construction.
