**Abstract:**

*Applying a variational method to a gaussian wave ansatz, we have derived a set of semi-classical evolution equations for SU(2) lattice gauge fields, which take the classical form in the limit of a vanishing width of the gaussian wave packet. These equations are used to study the quantum effects on the classical evolutions of the lattice gauge fields. © 1994.*
