This paper takes the basement of a project as an example,and this project is an ultra-long concrete structure.The calculation method of temperature stress is used to comprehensively grasp the structural deformation caused by temperature and internal force,and clarify the concentration position of temperature stress on the structure,so as to formulate corresponding structural measures in a targeted manner.At the same time,the post-cast strip and temperature constructional reinforcement are reasonably arranged.Through effective control in the environmental temperature difference,materials,concrete production process and construction,the construction period can be effectively shortened,the project cost can be reduced,and the generation of harmful cracks can be prevented,so that the ultra-long basement structure can achieve the seamless design goal and provide reference for similar projects.
