For the rigid self-waterproofing design of ultra-long basements,concrete structure design is the key to ensuring that the waterproofing design service life is not less than that of the main structure design.This article introduces a series of structural design measures to achieve rigid self-waterproofing design for a newly built ultra-long basement project in Wuhan.The three-dimensional finite element analysis software YJK is used to analyze the temperature stress of the ultra-long basement.At the same time,a structural design method is proposed to control temperature cracks in concrete slabs by configuring temperature steel bars,which can provide reference for similar engineering designs.
