高密度电阻率法在岩溶地区中的正演模拟
Forward Modeling of High-Density Resistivity Method in Karst Areas
摘要: 高密度电阻率法作为一种有效的地球物理勘探手段，在岩溶地区的地质调查中展现出了独特的优势。该方法通过向地下发射高频电流，并测量不同位置的电阻率变化，能够精确地描绘出地下岩体的电性结构，进而揭示岩溶地区的地下构造特征。在正演模拟过程中，我们首先根据岩溶地区的地质资料和地球物理特征，建立合理的地质模型。随后利用高密度电阻率法的正演算法，模拟电流在地下介质中的传播路径和电阻率分布，从而得到模拟的电阻率剖面图。这一过程不仅有助于我们理解岩溶地区地下电阻率的分布规律，还能为后续的反演解释提供可靠的依据，进而提高岩溶地区地质勘探的准确性和效率。
Abstract: As an effective geophysical exploration method, the high-density resistivity method has demonstrated unique advantages in geological surveys of karst areas. By transmitting high-frequency current into the ground and measuring resistivity changes at different locations, this method can accurately depict the electrical structure of underground rock masses, thereby revealing the underground structural characteristics of karst areas. In the process of forward modeling, we first establish a reasonable geological model based on the geological data and geophysical characteristics of the karst area. Subsequently, using the forward algorithm of the high-density resistivity method, we simulate the propagation path of current in underground media and the distribution of resistivity, so as to obtain a simulated resistivity section. This process not only helps us understand the distribution law of underground resistivity in karst areas, but also provides a reliable basis for subsequent inversion interpretation, thereby improving the accuracy and efficiency of geological exploration in karst areas.
