Exploration and Application of Drainage Pressure Reduction and Anti-buoyancy Technology for Basements
In this paper,taking the basement of a residential project in Fuzhou as an example,ABAQUS software is used to analyze the influ-ence of the spacing of drainage holes on the drainage and decompression effect.The results show that the drainage and decompression method can effectively reduce the buoyancy of basement water,and reducing the spacing of drainage holes can significantly reduce the pore water pres-sure of basement floor,and improve the anti-buoyancy safety.At the same time,based on the results of structural anti-floating checking and foundation pit seepage checking,the reasonable spacing range of drainage holes and related anti-floating safeguard measures are proposed,ai-ming at providing technical reference for similar projects.
