Abstract

The invention discloses an ultra-high density electrical method electrode planning method for eliminating polarization effect interference. In the method, the influence of the polarization effect in the ultra-high-density electrical acquisition process is considered. By optimizing the selection order of an ultra-high density electrical method power supply electrode and a measuring electrode, the interference of the polarization effect in the engineering is reduced, and the data acquisition quality is improved. In the method, the optimization process of electrode arrangement is transformed intoa global optimization problem, and individual diversity is maintained and the optimization quality of an algorithm is improved through global cross-update and two local mutation operations. The method can be optimized according to the electrode arrangement characteristics of the ultra-high density electrical method, is simple to implement, has convenience in calculation, and has high practicability in engineering.

Description

technical field [0001] The invention relates to the field of geophysical electrical prospecting, in particular to an ultra-high-density electrical electrode planning method for eliminating polarization effect interference. Background technique [0002] The high-density electrical method is an important geophysical electrical prospecting method. It adopts the idea of ​​array prospecting, uses the program-controlled electrode converter, and quickly selects the power supply electrode and the measuring electrode according to the type of measurement device set to achieve high-efficiency data. Acquisition has the characteristics of high observation accuracy, large amount of data collection, rich geological information and high production efficiency. The ultra-high-density electrical method is an improvement of the acquisition method of the high-density electrical method. It is not restricted by the measuring device in the traditional high-density electrical method, and can collect...
