Abstract: Soft foundation treatment is a key technology problem in highway construction; dry jet mixing pile is often applied to soft foundation treatment. By the in-situ test, the dissipation laws of pore water pressure in the course of dry jet mixing pile construction and the developing laws of soil strength along with time are studied. According to the numerical simulation analysis, the developing laws of pore water pressure along with depth and horizontal distance are obtained. The developing laws of the soil strength because of disturbance by the dry jet mixing pile construction are revealed from the test aspect and theory aspect.

Key words: in-situ test, numerical simulation, dry jet mixing pile, pore water pressure, soil strength around pile
