The embodiment of the invention discloses a risk evaluation method and apparatus in an N-X overhaul mode. The method comprises the following steps: receiving an identifier of a to-be-overhauled object input by a user, wherein the to-be-overhauled object comprises a network device or a link; determining risk objects corresponding to the business according to the to-be-overhauled object, wherein the risk objects comprise network devices or links; determining risk result values, risk probability values and risk exposure times of the business according to the risk objects corresponding to the business; and determining the risk value of an electric power communication network when the to-be-overhauled object is in an overhaul state according to the determined risk result values, the risk probability values and the risk exposure times of the business. By adoption of the risk evaluation method and apparatus provided by the embodiment of the invention, the risk value of the electric power communication network in the N-X overhaul mode can be accurately evaluated, when the to-be-overhauled object in the overhaul state.
