Super High-rise Building FoundationQ iao Lei?Abstract ] Mass concrete technology is a key technology in super high-rise buildings. Due to complex engineering conditions
and large cement hydrothermal coefficient, quality problems such as temperature deformation and cracking of concrete structures are
prone to occur in actual construction, which affect the safety and performance o f super high-rise building infrastructure. Therefore, this
paper expounds the technological process and operating points o f the mass concrete construction technology of super high-rise building
foundation, and proposes quality control measures, hoping to further improve the engineering construction level and give full play to
the technical advantages o f mass concrete.[Keywords ] super high-rise building ; mass concrete ; construction technology ; quality control ? ! ? 9 : ; N ? ! ? ? ? nh?: ?01 : ? ? 0 1
