Abstract
Crack control of basement roof slab is a key technical challenge to ensure building safety and durability. Based on the requirements of “General Specification for Concrete Structures” (GB55008-2021), this paper systematically analyses the causes of cracks, and puts forward a whole-process prevention and control system covering design optimization, low-shrinkage material proportioning, fine control of construction technology, and dynamic monitoring and repair. Through structural finite element simulation, wireless sensor network real-time monitoring, and carbon fibre fabric reinforcement test, the effectiveness of the multi-technology synergistic control framework is verified, and the engineering cases show that the crack width after repair is stable within 0.1mm, and the bearing capacity is increased by more than 30%. The study provides theoretical support for crack prevention and control in super-long underground projects, and looks forward to the direction of integration application of BIM technology and intelligent materials.
