Abstract

This invention discloses a method for calculating the electric field characteristics in the piping failure evolution process of an earth-rock dam. The method calculates the seepage field and electric field at different stages of the piping failure evolution process of the earth-rock dam. Based on the calculation results of the piping failure evolution of the earth-rock dam and the potential distribution of the earth-rock dam, the potential distribution characteristics and their variation laws of the entire evolution process of the earth-rock dam from no piping failure to the initiation of piping failure and the development of piping failure are obtained. This lays the foundation for developing a rapid inversion method for the piping failure evolution state based on electrical resistivity tomography (OTM) detection technology.
