Abstract
We used three-dimensional finite element analysis to simulate an X-shaped cast-in-situ concrete (XCC) pile-supported embankment with asphalt pavement under the load of moving vehicles. We investigated the dynamic stress transfer mechanism, the trapping effect of the embankment and XCC piles, and the asymmetric distribution of dynamic stress around an XCC pile. The results show that the embankment and XCC piles play an important role in spreading the radiated energy as a waveguide. The ground in the center is subjected to the majority of dynamic stress owing to the trapping effect of the embankment and XCC piles. There is also a significant difference between the dynamic stress in the flat and concave areas within up to two times the outsourcing diameter of the XCC pile.
