Abstract: Structures and structural members will be damaged seriously when basement rises up before the completion of the construction project. An engineering accident case whose structural members were cracked because of the floated basement were presented, the accident reason was analyzed and the related treatment scheme was proposed to solve this problem. In addition, the reinforcement measures of cracked structural members were carried out, the load path and construction procedures of columns concrete-replacing method were also discussed in this paper, which may offer some references to other similar engineering accidents.
