  The study of high energy gamma-ray bursts can be performed by large area air
shower arrays operating at very high mountain altitudes. ARGO-YBJ is a detector
optimized to observe small size air showers, to be constructed at the
Yangbajing Laboratory (Tibet, P.R. China) at an altitude of 4300 m. One of the
goals of the experiment is the study of Gamma-Ray Bursts of energies E > 10
GeV. This can be achieved using the "single particle" technique, more
profitable in the energy region E < 50 GeV, and the "low multiplicity"
technique, suitable to observe GRBs at higher energies. The sensitiviy of
ARGO-YBJ allows the detection of GRBs with energy fluences in the range 1--100
GeV as low as F~10^{-6} -- 10^{-5} erg cm^{-2}, depending on the spectral
characteristics of the burst.
