Abstract

Numerical model of post-grouting bored piles which are applied to specific engineering was built and analyzed, the result of numerical model was compared with the static test result of test piles on site, which confirmed the feasibility and rationality of the numerical model. By the numerical model, the influence factors of post-grouting bored piles used by a cable-stayed bridge under construction was analyzed, the result show that: (1) the bearing capacity of bored - pile could be improved through the post-grouting technology; (2) the Elastic Modulus of the solidified body is proportional to the bearing capacity of bored - pile, however there exists an optimum Elastic Modulus value; (3) the bearing capacity of bored - pile was affected heavily by the penetrating depth of the grout, there exists a reasonable range of grouting quality and grouting pressure.
