                                  Abstract: The construction method of the traditional concrete cantilever platform structure support system is limited by the construction conditions, and it is difficult to construct with high risk in the specific structure form and construction environment. Combined with the engineering case, this paper introduces a design and structural impact analysis method of the steel truss support system of the super high and long cantilever tube structure. Combined with the structural characteristics, the reasonable construction process is developed, and the installation points and pipe fitting methods of the steel support are pointed out, and the technical problems of the construction of the super high and long cantilever cast in place concrete structure are solved.
