  We study the prospect of determining the decay properties of the gluino in
the supersymmetric (SUSY) standard model at a 100 TeV future hadron collider.
We consider the case where the neutral Wino is the lightest superparticle. In
this case, the long-lived charged Wino can be used to eliminate standard model
backgrounds, which enables us to study the details of superparticles. We show
that, based on the analysis of the numbers of high $p_T$ leptons, boosted
$W$-jets, and $b$-tagged jets, we may determine the gaugino species and the
quark flavors in the gluino decay. With such determinations, we can obtain
information about the mass spectrum of squarks even if squarks are out of the
kinematical reach.
