Abstract:Taking a specific project as an example, the problems often encountered in the structural design of super-large waste incineration power plant were introduced, such as the selection of structural type and calculation software, anti-cracking design of super-long structure, the calculation of waste load, the seismic design and durability design of waste pond, the design of foundation, the calculation of equivalent uniform load on the floor of unloading hall, the temperature load analysis and design of super-long structure, etc. The structural stress and deformation of the front platform with rigid slab and elastic slab were compared respectively. The design suggestions were given as follows: the structural form of the main workshop should be determined after comprehensive analysis; elastic floor should be selected when the long and narrow floor was used as horizontal support of the wall of the waste tank; various means should be adopted to reduce the temperature stress and improve the resistance of structural components.

Keywords:waste incineration power plant; super-long structure; waste load; anti-cracking design; durability design
