According to the problems of geotechnical disaster, earthquake disaster, environmental wind disaster and fire encountered by civil engineering in Guangdong Science Center, this paper uses the combination of microstructure research and macroscopic structure research, the combination of shaking table test and finite element analysis, Hole test and finite element analysis combined with computer simulation analysis and other technical means to carry out the Guangdong Science Center saturated soft ground pretreatment, engineering seismic, wind and performance of the project design of fire protection and other engineering disaster protection technology research. This paper proposed the technology of “subdivision treatment” and the combination of dynamic and static water drainage consolidation methods to complete the seismic performance optimization design of the complex over-limit structure of Guangdong Science Center, and solved the main structure and the structure of Guangdong Science Center under extreme wind loads The safety of the envelope, the fire scene and the evacuation status of fire risk and fire load analysis were discussed. The research results provide the necessary parameters for the engineering optimization design of Guangdong Science Center.
