Indoor Model Test on Vertical Bearing Characteristics of Marine Muddy Cohesive Soil Cored Mixing Pile
The cored cement-soil mixing pile combines the advantages of mixing pile and reinforced concrete precast pile,and makes up for the shortcomings of both sides.It is a kind of deep muddy soft soil composite foundation treatment method that is being widely promoted.In this paper,through the indoor model test of vertical bearing capacity of single pile and composite foundation of cored cement soil mixing pile,the vertical bearing characteristics of equal core pile and short core pile are studied,and the variation relationship of single pile bearing capacity,pile side resistance,pile axial force and pile-soil stress ratio is obtained.The test results show that the cored cement-soil mixing pile has stronger bearing capacity of single pile,which can significantly improve the bearing capacity of traditional cement-soil mixing pile.
