Abstract: The present disclosure relates to a method for advancedly detecting a water-bearing hazard body in real-time based on vector resistivities. The method includes: acquiring potential differences of receiving dipoles on a shield machine in real-time based on a pre-constructed detection environment, wherein the receiving dipoles include first receiving dipoles and a second receiving dipole; converting to resistivities by using a formula for calculating resistivities in a steady current field according to relative positional relationships between the receiving dipoles and power supply dipoles and the potential differences of the receiving dipoles to obtain the apparent resistivities of the receiving dipoles; drawing curves of the apparent resistivities of the receiving dipoles by taking positions of the power supply dipoles as an abscissa axis and the apparent resistivities as an ordinate axis; analyzing the changing curves of the apparent resistivities and determining a detection result of an abnormal body.
