摘要
Abstract
The thickness of silt and muddy soil in the sluice of the auxiliary flood discharge channel on the east side of Airport East Road in Binhai Business District is more than 50 m.The thickness of soft soil is large,and the foundation treatment is difficult.Based on the analysis and comparison of four commonly used soft soil foundation treatment methods,such as vacuum combined surcharge preloading method,cement-soil mixing pile,bored pile and prestressed high-strength concrete pipe pile(PHC pipe pile),the authors recommend that the long and short pile composite foundation composed of large-diameter cement-soil mixing pile and PHC pipe pile is used in lock chamber,retaining wall and other buildings.The results show that after the foundation treatment,the bearing capacity of the foundation is significantly improved,the settlement of the building is small,the scheme is safe and reliable,and the investment is less.The research results can provide reference for similar soft soil foundation treatment.关键词
