Because of the shortage of urban construction land and the difficulty of parking,people develop and use the underground space on a large scale,this kind of basement structure design technology more difficult and more complex.Taking the 6 stories basement of Block B of a certain project in Xiamen as an example,there are many difficulties in the structural design of the basement,such as high anti floating design water level,high temperature stress,and the need for reinforcement of foundation pit support.In view of the above difficulties,through in-depth analysis and reasonable determination of anti-floating anchor design,the adoption of special waterproofing design prac-tices,the setting of appropriate post-pouring belt and calculation of temperature stress and other anti-cracking measures,combined with the engineering situation,the reasonable foundation pit support reinforcement scheme is adopted,hoping to provide reference for similar ul-tra-deep and ultra-long underground engineering development and design.
