Abstract

On the basis of summing up the advantages and disadvantages of the existing high-density resistivity instruments and combining with the requirements of urban underground space exploration, a set of multi-parameter parallel measuring high-density electrical system is developed. It has the characteristics of transmitting signal at one time, receiving signal by multiple electrodes at the same time, and measuring multiple parameters at the same time. Compared with the traditional high-density electrical instrument, it can effectively improve the working efficiency. the field test shows that the performance of the new electrical system achieves the desired effect. At the end of the article, the paper summarizes the advantages of the new electrical system and showed the suggestions on the development of high-density electrical instrument.

Key words： high density electrical method electrical instrument urban underground space exploration induced polarization method
