Interpretation of vertical electric sounding data in Ho Chi Minh City by Zohdy method

Abstract

Resistivity which is one of the physical parameters of material plays an important role in many fields of research and application. Especially in geotechnical field, it is a necessary parameter to estimate effect in underground constructions, protecting the buildings from electrochemistry and designing lightning-conductors, etc. This paper introduces the average resistivity maps of Ho Chi Minh city, built by the Zohdy method for the automatic interpretation of sounding curves based on a huge of VES’ carried out in Ho Chi Minh city. Then, the average resistivity is calculated by traditional formulas and Dudás algorithm.
