Abstract: This paper investigated the relationship between the maximum lateral deformation and the vertical settlement of dry mixing column composite foundation under embankment loads. The relationship is a bilinear one which is the same as that reported for natural soft ground. But for the dry mixing column composite foundation, the incremental ratio of maximum lateral deformation over vertical settlement at the second stage is much smaller than that at the first stage. This result is contrary to that reported for natural soft ground under embankment loads. The reason responsible for the difference is contributed to the change in the stress ratio of pile to soil. The analysis also indicates that the deformation of the second stage mainly controls the construction quality of embankment for the dry mixing column composite foundation. Based on the compiled data of dry mixing column composite foundation, the incremental ratio of maximum lateral deformation over vertical settlement at the second stage is about 0.115.

Key words: dry mixing column (DMC), composite foundation, lateral deformation, stress ratio of pile to soil
