We propose a sensitive way to test the anomalous HVV couplings (V = W±, Z0) of the Higgs boson (H), which can arise from the dimension-6 effective operators in a linearly realized Higgs sector, via studying the VV scattering processes at the CERN LHC. The gold-plated pure leptonic decay modes of the final state weak bosons in the processes pp → VVjj are studied. We show that, with an integrated luminosity of 300 fb-1 and sufficient kinematical cuts for suppressing the backgrounds, studying the process pp → W+W+jj → l+νl+νjj can probe the anomalous HWW couplings at the level of 0.01 - 0.08TeV-1 for the linearly realized effective Lagrangian.
