In this paper, macroscopic quantum tunneling (MQT) effect of Z2 topologicalorder in the Wen-Plaquette model is studied. This kind of MQT is characterizedby quantum tunneling processes of different virtual quasi-particles movingaround a torus. By a high-order degenerate perturbation approach, the effectivepseudo-spin models of the degenerate ground states are obtained. From thesemodels, we get the energy splitting of the ground states, of which the resultsare consistent with those from exact diagonalization method
