The invention discloses a structure of a shield launching portal and a shield launching construction method. The structure of the shield launching portal comprises shield shaft main structures. The shield shaft main structures are made of plain concrete walls. A shield tunnel is arranged between the shield shaft main structures. A building enclosure made of a plain concrete wall is arranged at the end of the shield tunnel. The horizontal section of the building enclosure is arched, and the building enclosure can automatically distribute water and soil pressure outside a shield shaft into a rock-soil stratum outside the shield shaft evenly. A plurality of glass fiber rib guard posts are evenly arranged in the building enclosure. The arched plain concrete wall can distribute the water and soil pressure from the outside of the shaft into the rock-soil stratum outside the working shaft evenly, so that the probability that the stress on the upper portion and the lower portion of a conventional sealing portal is nonuniform is lowered, and the self-stabilization capacity of the stratum is brought into full play; through the high tensile strength of glass fiber ribs, deformation of the portal and the stratum around the portal is effectively reduced; and under the existence of the sealing portal, a shield tunneling machine advances directly to cut plain concrete and the glass fiber ribs, and thus the risk of water gushing and sand gushing which are caused by dismounting of the sealing portal is avoided.
