In SU(3) lattice QCD formalism, we propose a method to extract gauge fieldsfrom link-variables analytically. With this method, we perform the first studyon effective mass generation of off-diagonal gluons and infrared Abeliandominance in the maximally Abelian (MA) gauge in the SU(3) case. Using SU(3)lattice QCD, we investigate the propagator and the effective mass of the gluonfields in the MA gauge with U(1)$_3 \timesU(1)_8$ Landau gauge fixing. TheMonte Carlo simulation is performed on $16^4$ at $\beta$=5.7, 5.8 and 6.0 atthe quenched level. The off-diagonal gluons behave as massive vector bosonswith the approximate effective mass $M_{\mathrm{off}} \simeq1.1-1.2\mathrm{GeV}$ in the region of $r =0.3-0.8$fm, and the propagation islimited within a short range, while the propagation of diagonal gluons remainseven in a large range. In this way, infrared Abelian dominance is shown interms of short-range propagation of off-diagonal gluons. Furthermore, weinvestigate the functional form of the off-diagonal gluon propagator. Thefunctional form is well described by the four-dimensional Euclidean Yukawa-typefunction $e^{-m_{\rm off}r}/r$ with $m_{\rm off} \simeq 1.3-1.4\mathrm{GeV}$for $r = 0.1- 0.8$ fm. This also indicates that the spectral function ofoff-diagonal gluons has the negative-value region.
