摘要
高密度电阻率法兼顾电剖面法横向分辨率高和电测深法纵向分辨率高的优点,其成像技术已成为继地震波层析成像和电磁波层析成像以后地学CT的重要物探手段,已广泛应用于水文地质和工程地质勘察、地下水开采、金属矿产勘探以及工民建等领域。为适应实际复杂地质条件下的数据处理与解释,排除干扰影响,本文就高密度电阻率法最小构造二维反演技术的理论与实现进行了粗浅探讨,并以几个应用实例说明了该技术的有效性和实用性。
Electrical prospecting has higher horizontal resolution of electrical profiling and higher vertical resolution of electrical sounding. And the resistivity tomography has become an important approach of geosciences CT that had seismic wave tomography and electromagnetic wave tomography. It has been widely applied in the fields of geological examination,ground water development,mining exploration,et al. To fit the complex structural data interpretation and inversion,and to remove the 'null space' in the interpretation,the paper discussed 2D least construct inversion theory and its implementation procedure. Then it explained the validity and practicability by two application examples.
