Study on the Calculation of Bearing Capacity of Dry Jet Mixing Pile Composite Foundation
Firstly,the mechanics of dry jet mixing pile composite foundation is studied deeply.The strain and stress of the piles and soil is deduced according to the theory of round hole expansion,which considered the deformation coordination of the piles and soil.Then a calculation for the bearing capacity of dry jet mixing pile composite foundation is established based on the stress ratio of the piles and soil.Finally,an in site test is carried out to verify the calculation,and the comparison shows the calculation is in agree with the test.
