摘要：

A new theoretical formula for soft ground bearing capacity is derived. This formula is based the unified strength theory, and the effects of consolidation, intermediate principal stress and the coefficient of lateral pressure are taken into consideration. According to this formula, an improved calculation method of the critical filling height of embankment is proposed. In addition, the calculation method is applied to railway subgrade filling test data to check its feasibility. The calculated results show reasonable good agreement with experiment results. The new formula may be used as the theoretical basis for determining the safe filling height at different phases of railway subgrade works. ©, 2015, Editorial Board of Jilin University.
