高密度电法的三维数据场可视化

高密度电法是重要物探方法之一，由于它具有施工快捷、分辨率高、可靠性好、图像直观等优点，已被广泛应用于寻找金属非金属矿、地下水及各类工程地质勘察等众多领域.目前，该方法在数据资料处理方面还局限在二维图像.本文结合在山西阳泉复杂采空区利用高密度电法和高精度GPS测量联合勘察的工程实例，基于WinDisp软件平台，实现了高密度电法的三维数据场可视化，构建了视电阻率参数下的三维地质体结构模型，并且可以任意移动、旋转、切片、分层显示、实时显示真实地理坐标等.该模型客观、真实、形象地反映了电性异常的三维地质结构，为高分辨率预测复杂采空区的空间分布特征提供了直观、可靠的资料.

The visualization of three dimension data field sof high-density electrical technique

High density electrical technique is one of the most important geophysical exploration methods, because it possesses the advantages of rapid operation, high resolution, high reliability, intuitionistic image, etc. Upon to now, high density electrical technique has been widely used in lots of exploration fields, such as metal and non-metal resources, underground water and various engineering geology. However, the technique is restricted two dimension imaging level in data processing aspect. Based on the WINDISP self-contained software package, the paper has realized the three dimension data field visualization with the example of detecting complicated cavity by using high density electricity technique and high-resolution GPS survey. It has constructed three dimension geological structure model which can be moved and rotated randomly. Moreover, it can be sliced and viewed in layers. It can also display the true geographical coordinates in real time, etc. The model has truly,objectively and visually reflected the three dimension geological structures of electricity abnormality, and it has provided the intuitionistic and reliable data for predicting the space distribution character of complicated cavities with high-resolution.
