摘要
采用声纳水声学固有的水下探测功能,开发了水下流速矢量声纳测量方法。首先从工程渗流的实际应用出发,提出了"渗流矢量能量与质量测量模型"与大数据解析成像的水文地质参数结合,解决了渗流工程中的一系列技术关键问题。然后整合了能直接用于天然流场与人工流场的水文地质参数现场测量的软硬件成果,提高了水文地质参数原位测量的渗流场、矢量场、水力梯度场的真实性刻画,避免了传统抽压水试验对真实水流的缺失与影响。实现了探头的数据采集、声纳法测量、计算机功能界面显示,完成了三维动态可视化水文地质参数成像分析体系。应用结果拓展到孔隙水、裂隙水和岩溶水的各个水文地质单元纵横断面的补排关系和地下工程渗漏水缺陷的定量与定位测量。
Using the inherent underwater detection function of sonar underwater acoustics, the underwater velocity vector sonar measurement method is developed. Starting from the practical application of engineering seepage, this paper puts forward the "seepage vector energy and mass measurement model" and the results of hydrogeological parameters of large data analytical imaging, and solves a series of key technical problems in seepage engineering. The results of software and hardware that can be directly used in the field measurement of hydrogeological parameters of natural and artificial flow fields are integrated, which improves the authenticity of seepage field, vector field and hydraulic gradient field in the field measurement of hydrogeological parameters, and avoids the impact of traditional pumping test on urban environmental settlement. The data acquisition of the probe, sonar measurement and computer function interface display are realized, and the three-dimensional dynamic visualization of hydrogeological parameters imaging analysis system is completed. The application results can be extended to the filling and draining relations of vertical and horizontal sections of each hydrogeological unit of pore water, fissure water and karst water, and to the quantitative and positioning measurement of leakage.
