Abstract: Highway subgrade often damage when put into operation for a period of time, part of the reason from overloading. This paper employ semi inverse method to calculate subgrade stress component under full-ｌｏａｄ, taking a road as an example, subgrade stress component obtain, verifying the correctness of the formula.

Keywords: Road Subgrade; Stress Component; Semi Inverse Method; Full-ｌｏａｄ
