Abstract: Because of the solution method unreasonable,the settlement calculation precision for the dry jet mixing pile(DJMP) is unconvincing. Based on the load transfer behavior and the characteristic of DJMP, using Boussinesq solution and Mindlin solution, the additional stress is calculated. Different calculation methods are used to analyse the stress distributing characteristic for stabilized layer and the underlying soft layer. The correlative formula is derived. Calculation result shows that the Boussinesq－Mindlin united solution method is reasonable and feasible.

Key words: dry jet mixing pile, composite ground, Boussinesq-Mindlin united solution, load transfer behavior
