The invention discloses a simulation method oriented towards a distribution line operating maintenance process. The method comprises the following steps of resolving a work flow and establishing a layered simulation rule base; reading an initial three-dimensional scene to form an initial condition; reading simulation rules which are the same as the current layer number from the simulation rule base and counting the simulation rules; judging the number of read simulation rules and triggering a respond operation instruction for executing the simulation rules; judging whether the read simulation rules are completely executed or not; if so, adding one to the current layer number, then reading simulation rules which are the same as the current layer number from the simulation rule base and counting the simulation rules until the number of read simulation rules is 0; and if not, triggering the respond operation instruction for executing the simulation rules until the read simulation rules are completely executed. Simulation steps are described by simulation rules, and the simulation logic and steps can be flexibly changed, so that better flexibility and university are realized.
