Analysis and reinforcement of a basement floating accident
This paper presents the case of floating accident after rainstorm during the construction of a project.Analyze the causes of acci-dents from a design perspective by combining survey,construction,and accident site data.The main reasons are that the short-term water buoyancy during construction exceeds the anti floating bearing capacity due to premature closure of the post pouring zone,incomplete top plate soil covering,poor quality of backfilling construction,inadequate drainage conditions in the foundation pit and surrounding areas,etc.In order to repair structural damage and deformation,some treatments have been developed.Such as opening holes for water discharge,loading the basement with sandbags to sink and reset it,component reinforcement,adding anti floating anchor rods,and soil grouting.In ad-dition,several key points for basement anti floating and repair were summarized,providing reference for the design and construction control of other similar projects.
