Based on the Mohr-Coulomb strength theory, a new formula of critical load of subsoil with K_0≠1 is deduced. This method avoids artificial overestimated results due to the assumed K_0≠1, which can reflect the essentials of subgrade bearing capacity more accurately. Example calculations indicate that the new formula is more reliable than the old formula.
