The invention discloses a suspend dome structure multi-prestressed construction method used in construction field. The construction method is that: firstly, a central pressure ring, an upper radial bar and edge elements are arranged on an upper layer; secondly, a lower radial rope, a lower ring rope and a strut are arranged on a lower layer; thirdly, prestress is applied in the structure by stretching the lower ring rope or stretching the lower radial rope or adjusting the length of the strut; fourthly, a ring bar is arranged; fifthly, an external load is applied on the structure. Compared with the structure formed by a traditional method, the suspend dome structure formed by the invention reduces peak pressure of elements with concise force, even changes a part of elements from a pressure bar to a tension bar, avoids instability of elements, at the same time enhances the entire stability of the whole structure and enlarges the ultimate bearing capacity. Furthermore, the invention leads a more even distribution of internal force of the upper layer network shell bar elements, is helpful to the unity of the elements and convenient for design and construction, at the same time, the invention reduces the applied prestress value and reduces construction difficulty.
