  The tri-boson production is one of the key processes for the study of quartic
gauge couplings. Next-to-leading order (NLO) corrections are mandatory to
reduce theoretical uncertainties. In this study, the most up-to-date
predictions including NLO QCD and NLO EW corrections to the total cross section
and distributions of the WWZ production at the LHC are presented. We show that
the QCD correction is about 100% and the EW correction is of a few percent at
the total cross section level. The EW correction however becomes significant in
the high energy regime of the gauge boson transverse momentum distributions.
