To study the impact of explosive radius on bearing capacity of loess soft foundation reinforced with blasting compaction method,the paper firstly simulates explosion effect and bearing capacity with LS-DYNA and ANSYS,and obtains the characteristic value of the single-pile composite foundation with blasting compaction method. Then,it verifies the feasibility of the model through bearing capacity theory formula and outdoor high bucket test,and studies the impact rule of explosive radius on bearing capacity of single-pile composite foundation. The result shows that the characteristic value of bearing capacity of the single-pile composite foundation will become smaller when the radius gets larger.
