The invention discloses a high-altitude comprehensive construction method of a big-cantilever steel truss structure. The high-altitude comprehensive construction method includes the following steps of a, constructing a building structure body, and pre-burying a cantilever truss bracket on an outer-side major structure, where a cantilever steel truss needs to be mounted, on each floor; b, setting up a cantilever construction platform on a floor slab below the cantilever truss on the first layer, and setting up an operating scaffold through the cantilever construction platform; c, utilizing a crane to hoist the cantilever truss on the first layer to the cantilever truss bracket on the first layer, enabling construction personnel to be in place on the operating scaffold, welding the cantilever truss on the first layer with the truss bracket, completing construction of the cantilever truss on the first layer, and demounting the operating scaffold on the first layer.
