Abstract The strict control standards for post-construction settlement of high-speed railway require high accuracy of settlement calculation，and the improvement of settlement calculation precision directly results from the high computational accuracy of additional stress，which makes the issue of calculating additional stress of significant importance. Differing from the assumption that the load acting on soil between piles in geosynthetic reinforced pile supported embankment presents uniform or symmetrical triangular distribution in the present study，the parabolic distribution form is proposed. Starting with the distribution function of strip parabolic load acting on soil between piles，the computational formula of additional stress caused by strip parabolic load in elastic foundation is put forward. The theoretical derivation is proved to be correct and reliable by numerical simulation；and the rationality and superiority of the computing method of additional stress are guaranteed by case study. The research achievements can provide reference for improving computational accuracy of additional stress along with settlement in geosynthetic reinforced pile supported embankment.

Key words： subgrade engineering geosynthetic reinforced pile supported embankment additional stress strip parabolic load Boussinesqs solution
